DVPREL1 unavailability of accessing T in PCOMP card

Hello,

I have a model that includes PCOMPs and I have already ran the free-sizing optimization. After opening the second file and transforming the derived STACKs and PLYs into PCOMP entities and values, I followed the process as it is described in the tutorial, but after output there exists an error message stating that there is no 'T10' field in the property card, which is impossible, because it is included in the output file. I have 6 PCOMP properties with approximately 50 layers each of them. The error message concerns the DVPERL1 card where after 9th layer's thickness there seem to be an unavailability to get the value from the 10th layer.

Can you suggest me anything about overcoming this problem? I hope you can answer my question as soon as possible.

Best regards,

Christos

PS: It is vital not to change the model properties from PCOMPs to STACKs and PLYs

Hi @cvenetis

Could you please share the .out file and the model file using the file transfer link available in my signature?

Hi Christos,

Could you please point me to the tutorial you are referring to?

Hi Prakash,

It's a tutorial that has to do with a skateboard with title: 'Composite Optimization of a skateboard with OptiStruct'

Hi Christos,

I updated the DVPREL1 13200 which the error is referring and I am able to run the model now.

Hi Prakash,

Can you please describe me what kind of problem existed??

Looks like solver didn't recognize the thickness variable for property 1.

Updating this worked.

Hi Prakash,

Can you send me back the output file to check it? Because it still doesn't seem to work for me

Hi,

Here is the out file, I had to stop the run as soon as analysis started.

Hi Prakash,

In fact the main problem is that I use a different pre-processor from Hypermesh, but I use OptiStruct feature as an optimization solver, that's why I want to check the *.fem file if there are any differences from what I have sent to you.
