Topology Optimization for PCOMPG

Hi ,

 

 I have performed topology optimization using PCOMPG. So I have created the PCOMPG using hyperlaminate option with +/- 45 deg orientation for alternate layers with total thickness of 5 mm (each ply thickness is 0.25mm). After solving the model, in post processor window I am getting option for base thickness (attached the screenshot) with thickness of 45mm throughout all the iteration.Please clarify why it is showing that option and that value.

 

Also I need clarification on PCOMPG, if I use topology optimization on PCOMPG whether the effect of overall & individual  thickness  and Ply orientation will be taken into consideration ?

In the second attached image the topology optimization results for individual plies are show.Is it possible with PCOMPG?

 

Thanks in advance

    Hi,

     

    This is strange:  base thickness is available only for PSHELL type (not PCOMPG), toggle to specify a non-zero value for the base thickness.

    A component’s total thickness is the same as the thickness given in its PSHELL card.  The default base thickness is 0.0, but you can click the toggle to enter a different base thickness.

    Thanks for the reply. I am clear about the PSHELL , but my query is why it is showing for PCOMPG ( i didn't mention any base thickness value for  that)
