Hi Everyone

        I am new to hyper mesh ,i am using hyper mesh as a pre processor for structural analysis . I have a solid element only,  one side i want to fix for that i have created a not set using  (Entity set >Nodes) . I want to apply pressure on other side but pressure can be applied to element set only  so how to create surface element set in solid meshing but i don't have surface elements .....

 

 

Advance thank you for fast reply

 

Warm Regard

    Hi Venkat,

     

    You can extract faces of the other side of the solid elements and move those faces (shell elements) into a different component.

     

    Goto Tool>>Faces>> select solid elements>>Find faces

    Hi Prakash

                I have created the shell element component and now i can apply the pressure load Than I have specified the properties to solid element but for shell element i don't have property to specify because i have only the solid section. my solver is abaqus while solving it shows error the property is not defined for shell component (sectional property like thickness).

    My problem is i have only the solid  section with element,I can apply a  fixed, and force boundary condition to not sets but pressure , surface heat flux , radiation boundary condition can be applied only to the element sets not for node sets .I just want to create  sets than i can apply the boundary condition quickly

     

    Warm Regards

    How i have to create the surface set?

    How to calculate the area on which the pressure is to be applied?

    In the following problem, blue colour block is fixed and 1000 Newton force is to apply on green block face as shown, I wanted to apply the force in form of pressure so that by using pressure*area=force i  can apply force evenly on the surface without considering the mesh density variation.The load here is time varying 1000 is peak value.

     

     

    Thank you

    Hi,

    You can create a contact surface and can apply pressure on the same.

    By Tool>Faces create a surface and using mass calc option find the area.

    If i want to apply force in particular direction?what we can do ? Like convex surface.

    You can specify diection by N1N2N3 in panel force or pressure
