Hello,

I would like to extract the a pressure force on a surface based on a reference frame, but I guess it is not possible, i.e. the x/y/z components of the 'PressureForce' are always in the direction of the model global coordinate system.

In the attached example I'd like to extract the resulting force on the surface along the X-direction of the reference frame shown on the attached image (that is not the global/model one).

Please verify!

Hello steelxpert

I will check it and get back to you.

Hi Naresh Patre

Can you please update me on this matter?

Hello steelxpert

There is no direct option to select a local reference frame while extracting pressure force. However, I am checking if it is possible to achieve the same via expressions and will let you know.

Hello Naresh Patre

Thank you, that would be great.

Hello steelxpert

I see that the reference frame is aligned along the geometry face. So, won't the variable "PressureForce.mag" (Pressure Force Magnitude) give you the resultant force normal to the selected geometry faces? 

You can also use below expression which eventually gives you the resultant pressure force (Pressure Force Magnitude)

sqrt((pow(PressureForce.x,2)) + (pow(PressureForce.y,2)))

hello Naresh Patre

Thank you for your answer.

Basically, my original question concerned more the possibility of having the Pressure:force components aligned to a user-defined Reference Frame rather than concerning the solution for that specific problem/geometry.
