Pressure Loading in HyperMesh

Hi

I have a model of a socket of an amputee. The weight of the amputee was divided by the internal area to calculate internal pressure.

I have meshed it with 2d shell tria elements.

Now how should I model this pressure in HyperMesh.

    Hi,

    If you are using optistruct solver to carry out analysis.In optistruct user profile you would find option to apply pressure on elements.pressure acts on element normal direction.

    Analysis page:pressure option is available.

    Select element and enter magnitude of pressure.

    Thanks Rahul sir.

    In Pressure Panel

    1) There are two options 1) Normal and 2) A Select a Vector. Please elaborate that. 

    2) it selects the load type as PLOAD4(Default). What is the meaning of PLOAD4 and other.

    Hi,

    1.If model having curvature and uneven phase.please use normal option.If pressure applying region is in one plane use vector option.But in your case you use normal option.

    2.Pload4 type is used for hexa penta tetra quad and tria element.

    Pload is for only quad and tria.

    Pload1 for Bar and beam element.

    Refer Optistruct solver user guide for detailed information.

    Regards
