Material undefined error in Import Cell Data

[Nori]

Hi, 

Many thanks for the recent update of PetraSim 2025-2. 

I tried the new feature of Import Cell Data, but failed with the following error when I tried to implort material data.

 

Error: 4 Material is undefined within Lookup Table.

 

I have a CSV file containing X,Y,Z,Material columns. In the Material columns, the data have values from 0.0, 1.0, 2.0, and 3.0.

In PetraSim, I defined 4 materials with material code of 0.0, 1.0, 2.0, and 3.0.

I think I set them correctly, but there can be mistake somewhere.

Does the error message suggest that there is a problem in material definition in the Petrasim data? 

Or do I completely misunderstand somehting?

It would be nice if someone can help to fix the error.

 

Thank you in advance,

Nori
