Hello everyone,
I am trying to run what I would call a “simple” tensile simulation using ductile damage initiation and damage evolution. My reference is the following discussion:
"DUCTILE DAMAGE INITIATION AND EVOLUTION (INIEVO) IN OPTISTRUCT IMPLICIT-EXPLICIT - Altair Community"
I am working with the implicit solver. However, I encountered something quite strange: the model does not run — neither my own model nor the example provided on the website.
I am wondering whether this issue is related to the version I am using:
OptiStruct Input Deck Generated by HyperMesh Version: 2023.1.0.21
I noticed that the example model provided in the link was generated using:
I checked the download options, but there does not seem to be any way to download version 2023.1.0.22 specifically.
After inspecting the .fem file, I identified that the issue in my version appears to be related to the following line:
+ CRI INIEVO 101.0 102.0 0.0 0.0 0.0
This line assigns the damage model to the MATS material. However, it seems there is no option to define this properly in the GUI, and when I try to include it manually in the .fem file, it gets rejected during execution.
The example model uses an include file, which defines the following section:
%---------------MATS1-------------------------------MAT1 1 206000 0.37.85E-091MATS1 1 1 PLASTIC 1 1 1 DAMAGE 101 102$$$$ DMGINI Data$$DMGINI 101 DUCTILE 0.25 0.33 1
Later in the same file, damage is referenced again, this time using MATF:
$---------------------MATF----------------------------MAT1 2 206000 0.37.85E-091MATS1 2 1 PLASTIC 1 1 1MATF 2 DAMAGE 0CRI INIEVO 101 102
So my questions are:
- Is this issue related to the version difference?
- Are these files incompatible with certain versions, or should they work in 2023.1.0.21?
- What should I do to run this model successfully in my current version?
- Do I need to upgrade? If so, to which version, since 2023.1.0.22 does not appear to be available for download?
I would really appreciate any clarification.
Thank you in advancea.
Alberto
