How to request grid point force balance output with GPFORCE card.

GPFORCE request grid point force balance output




Steps to follow:

1.Right click blank area in model browser

2.Go to Create>Cards>Output

3.This will open Create card panel

4.Scroll own to find GPFORCE. Check box in front of GPFORCE to enable GPFORCE

5.Provide number of GPFORCE request needed in GPFORCEORCE_NUM field

6.In first output request specify Format as H3D and format OPTI for second.

7.GPFORCE in requested In format H3D and ASCII(.gpf) format for ALL nodes and subcases.

8.In options you can user define grid set (SET_GRID).


Consider following simple example of cantilever beam with concentrated force of 100N at free end.



In ASCII (.gpf) file The value for reaction forces and moment is provided for each grid for for each load factor.

Same results can be observed in H3D file reaction forces and moments in respective direction.
