Hello, I am intending to set up a numercial model in Abaqus of an FDM process with a simple specimen, but I want to cumulate the heat flux of each element and correlate this with the Young's modulus using a degradation factor. I am using Abaqus plugin AM-Modeler to set up the FDM process. Furthermore, I use an USDFLD subroutine to store the HFL in an SDV in the heat transfer step and an UMAT subroutine to degrade the material propterties in the static step. On the one hand, I can run an Abaqus model built up with the AM-Modeler plugin. On the other hand, the subroutine works perfectly in a dummy model. But I cannot run them in the same model.

I am pretty sure, this is related to the env-file (attached) which is necessery to run the plugin. If this env-file is not in the working directory, I get the error: "USER SUBROUTINE UEPACTIVATIONVOL IS MISSING". If the env-file is in the working directory, everything works fine. But when I include the subroutine in the run, I get the same error. May you have any suggestions, how I could solve this problem? May you know what this env-file is doing? Kind regards Daniel Köhler
