ansys workbech structural- difference between pressure and surface force application

"Pressure" is always normal to the surface. "Surface force" can be applied in any direction. As example of a surface force that is not normal to the surface would be snow loading on a sloping roof - ...

How can I reduce the computation time required to simulate a brain tissue penetration model?

Given the subject matter my gut tells me to take the time to compute once you've triple checked your conditions. What material properties are you using? You can alter the mesh to decrease cpu usage as ...

How to determine time taken for tyre to deflate using CFD analysis?

I don't think CFD is the right tool. You can use an orifice equation, say from ASME, to calculate flow rate from inner and outer pressure. This takes the form of: $$\dot{m}=\frac{EC_D}{\sqrt{1-\beta^4}...

Why should I use a contact between two glued bodies in FEA when I can directly merge the mesh nodes between them?

Merging the nodes is equivalent of a continuous body (see welded). Using a contact definition, means that there are two separate surfaces which are connected through a layer/thin film (although this ...
