I would like to perform a derivative operation on an array.

The first array is the values of a dimension. The second array is the time.

How can I perform delta_Y / delta_time? 

It would also be great if is there a guide for writing valid actual expressions in GOM.

I would like to evaluate measures like principal strain, strain-rate in a certain direction over a line through the deformation scenes.

I would define a line on a surface component, and I would let the software to evaluate the desired measure through this line with a desired discrete number of points, over whole deformation scenes.
 

Is this possible?

Greetings,

I am currently performing a tensile test on a cylindrical specimen and using the available tensile test analysis script. However, I noticed that the script is designed only for rectangular and elliptical specimens.

Could you please let me know if there is an existing script available for cylindrical specimens? If not, I would appreciate guidance on how to correctly define the cross-sectional area of a cylindrical sample for accurate stress calculation within the current framework.

Thank you for your support.

I'm using Aramis 12M and Corelate cannot identify any facet on the initial/referent stage (I tried with all settings, sizes, filters...). I also recalibrated sensor. 

Any help is welcomed,

Best regards. 

I am using GOM correlate 2021 and I want to do FEA analysis. I am using ABACUS software for FEA but not able to Import the data from ABACUS software that can be use in GOM correlate 2021. I got .odb file but this file  not work when I run the FEA import script in the GOM correlate software . I watched one webinar in that it has shown that we have to run the python script to import the FEA data from the ABACUS software. Please help how I can export the FEA data from ABACUS and use it for FEA comparison in the software.

I am currently working on a project to correlate DIC data with FE models from ABAQUS within Zeiss Correlate.

Our team is using Abaqus, but our stress engineers use .sim files rather than the traditional .ODB format. I am aware of the existing Python script that converts ODB files into GOMXML for import, but is there an updated script or an internal Zeiss addon that can handle SIM (3DEXPERIENCE/Abaqus) file conversions to GOMXML? Alternatively, has anyone successfully scripted a conversion from STL to GOMXML?

Any insights on this would be greatly appreciated!

I use Inspect correlate pro. I did a measurement that worked fine. A few minutes later I wanted to perform another measurement, but I had this message "Switch to the workspace set up and configure the measuring volume".  I already had this message when I made an update (Inspect correlate to Inspect correlate pro). This consisted of making a calibration, just after declaring a measuring volume (a gom object in my case). The problem is that the icon "calibrate" is not active anymore in the workspace "set up" (see the attached file)? I analyzed my sensor. It looks fine.

Anyone has a suggestion?

In preparation for doing a 2D strain analysis, I would like to change the default time step (1 s) for all stages (imported as an image series) to match the real time step (0.00005 s) in the experiments. Previously, I have been able to do so by following these steps: "RMB on the time line -> Manage Stages -> Select all stages in the pop up window -> Edit Time Stamp".

However, for some reason, I cannot longer select all stages in the pop up window. The normal procedure (1. click on first stage, 2. press and hold Shift key, 3. click on the last stage) does not work anymore. 

Is this a bug on the software? Is there an alternative way to edit all time stamps simultaneously? 

I am using the pro version of Zeiss Correlate, Zeiss Inspect 2025.3.1.6

Thank you in advance

As the number of perforations is large and the total time needed for all the recomputations is rather high, I am interested in the possibility of defining a script to create the surface component with its entire geometry, as seen in the attached image.

Otherwise, is there a possibility of importing such a component from some external file or otherwise (procedurally) without having to perform successive recomputations?

Thank you!

 I would like to ask if you are using the ISO 16808-2022 version in the latest Bulge test script?  

I’m trying to perform a strain analysis on an analogue tectonic experiment, but it seems that Zeiss Correlate avoids the areas where heavy deformation occurs. Is there any way to fix this issue? These are actually the most important regions for the experiment.

Also, since the experiment was conducted in 2006 without considering optical strain measurement, the pattern quality is quite poor. However, there are very clear grid lines, if that helps in any way.

I am new to ZEISS Correlate and would like to ask whether the software can measure crack length frame by frame from captured images during a test.

I have a sequence of images with a clear crack path. I know the fixed starting reference point, and I can visually identify the crack tip moving in each frame.

What I want to achieve:

• Define one fixed reference point that remains constant in all frames.
• Define one moving point (crack tip) that the software automatically tracks across all frames.
• Have ZEISS automatically calculate and export the distance between these two points for each frame (crack length vs time).

It would be very helpful if someone could recommend the workflow in ZEISS Correlate to set up this measurement and explain how to export the distance values for all frames as CSV/Excel.

Thanks in advance!

I'm currently performing strain analysis on a 2D specimen subjected to a uniaxial tensile load using Digital Image Correlation (DIC). I’ve encountered an issue: the strain in the Y-direction appears negative on the upper half of the specimen, which is unexpected under tensile loading.

I suspect this might be due to specimen slipping during the test, possibly at the grips.

Has anyone experienced a similar issue?
Is there any post-processing method or correction technique in DIC software (e.g., filtering, coordinate transformation, reference frame adjustment) that could help address this?

I've attached an image of the experimental setup and the strain result for reference.

Any advice or insights would be greatly appreciated!

Thank you in advance.

ich habe eine Frage bezüglich ZEISS CORRELATE.

Ist es möglich, im Report eine Anzeige zu erstellen, die zeigt, mit welcher Herzfrequenz die Aufnahmen gemacht worden sind?

Vielen Dank im Voraus für eure Hilfe!

How can I fill these gaps effectively with interpolation? Do I need to do this operation for all the visible stages one-by-one until necking and failure? So far I tried the options Section>Close gaps, Mesh>Repair, Mesh>Close holes interactively but could not proceed fully with any of these options.

ich bin auf der Suche nach dem Skript für das Aramis LED Beleuchtungssystem. Weiß jemand, wo ich dieses herunterladen kann?

Vielen Dank im Voraus für eure Hilfe!

does someone know how I can calculate the strain of each single facet and export this?

Thank you!

Is the same thing possible in the new correlate software?

Cannot find any info on this topic.

I'm trying to calibrate one and another time with a CP20/175 panel for a 2D measurement, and all times the final message is MSensorCal-0231: The pre-orientation failed. However, alll the recorded images are checked (green tick) by the software, and the orientations found completely correct. What could be the cause of the error? Any suggestion? 

Thanks!

I would like to keep track of a distance between the two certain marked lines during deformation of a specimen, the specimen cannot have a speckle pattern, but only marking lines.

Let's say, I have a specimen where it is not possible to apply a speckle pattern. However, I can apply visible lines with a marker. These lines would then play the role of a physical touching probe extensometer. When I record the deformation of the specimen with marked lines, does Aramis offer an interface so it would be possible to compute the engineering strain over the distance between the marked lines ?

I am searching for high-quality camera for my DIC.

Do I need high signal linearity value of  camera?

Which is the best value of signal linearity?

I consider ZL41_Wave_sCMOS and AOS High Speed.

Have you had experience with such equipment?

Which one do you recomend?

Looking forward for your reply.
