Optistruct error #802

Altair Forum User

Hi! I recently started using hypermesh and Optistruct and I cama across error #802 as shown below:

 

*** ERROR # 802 ***

 Repeated factorization failure due to panel limitations on pivoting.

      Solver error no. = -513

            subcase id = 1

    default panel size = 256

  increased panel size = 4096

 Please increase panel size by PARAM,PNLSIZ and rerun the problem.

 

I'm using hypermesh 2017.3 and I can't seem to find 'PARAM,PNLSIZ' anywhere... How can i solve this problem? Also, what can cause this issue, as for me the error description is not sufficient to understand what might be causing the problem...

 

Thank you in advance!
