Hi Vrushang,
Yes, you can use PBEAML property and DIM2 will be your design variable.

@Prakash Pagadala Thank you sir for help.
I attached hm and fem file for this problem:
when i run analysis, it gives me error,
ERROR IN Analysis
In .FEM file it write this lines for PBEAML properties:
$$HMERROR: Only OS Solver Standard Sections are supported.
OptiStruct gives this error:
*** ERROR # 1479 *** in the input data:
Incorrectly formatted numeric data in field 9.
(If it is a character field, it should start with a letter.)ERROR IN Optimization setup
When i try to create DIM2 as a size design variable from Optimization>size>generic Relationship
i can not get the DIM2 option. (Image for this is attached as opti.png)
If DIM2 is not possible with GUI, I can do that with TCL script.
but is there any way to access this from GUI.

Looks like you have used HyperMesh section. Please use OptiStruct standard section to create beam using HyperBeam.
