v1.4.1 runs this model
all subsequent versions fails

It’s a generic CalculiX error. Try exporting the input file and submitting this simulation in the same version of standalone CalculiX. Instructions here: Using standalone CalculiX
Was it the same version of CalculiX as the one used by PrePoMax which didn’t work (possibly, use 2.21) ? Maybe there were some other differences like the number of CPUs or solver (Spooles/PaStiX/Pardiso and so on). I’ve even seen issues in CalculiX where the analysis worked in some runs and failed in others.
v1.4.1 points to a ccx_static
v2.0.0 points to a ccx_dynamic
I downloaded from the link you provided to get the ccx_static 2.21
I can use this standalone or point the settings to this file, both solutions work
In summary this works for Prepomax v2.0.0 as shown or v2.0.1 dev
But as downloaded, pointing the executable to the ccx_dynamic file, did not work in either Prepomax v2.0.0 or as shown here v2.0.1 dev
What if you submit it outside of PrePoMax using this ccx_dynamic executable referenced in PrePoMax settings ?
I can confirm that it also works for me for static and dynamic versions of CalculiX 2.21.
Analysis fails referencing the dynamic executable in prepomax
standalone ccx_dynamic from the calculix link gives
Some libraries are missing. Try downloading them from here: https://staff.tu.kielce.pl/rokach/instr/misc/ccx_220.7z
Might be good to ask about it on the CalculiX forum since it’s not a PrePoMax bug and there you are more likely to find someone with the same issue or even a solution.
If I specify spooles solver with the prepomax ccx_dynamic executable I get results
With the calculix_static executable I can keep as default or use pastix or spooles and get results
So maybe only Pardiso fails. Did you try PaStiX with ccx_dynamic ?
