Problem with tutorial

Hello everyone,

My name is Maciek.

Currently, I am learning FEA from YouTube tutorials by FEAanalyst.

I encountered a problem with tutorial 49. I have checked that I entered all the information correctly, but when I run the calculation, I get an error: “*ERROR in umat_compression_only: the Young modulus is too small.”

I assume that the issue is related to the manual keywords in the CalculiX keywords.

I am attaching a link to my Google Drive where I saved the .pmx file associated with the tutorial where I have the problem.

Thank you for your help!

It seems that you shared files from a different tutorial (42).

Sorry,
Here is proper link

You have to remove the asterisk from the line under *User material:

It should be:

*User material, constants=2
25000, 0.1
