## Convert pressure (Surface load) to nodal force

Dear all,

Currently, I have a FE mesh and want to apply pressure load on part of the surface.  Anybody has suggestions on how to convert the pressure load to nodal force theoretically and numerically?

Any help would be appreciated.

Thank you very much.

There are several possibilities for the realization of the presure load.
For
example, when I apply a pressure to an area (lets say, thin rectangular
plate) the area of the plate grows during the deformation process. One
possibility is to keep the pressure per unit area constant (in this case
the total force acting on a plate grows during the deformation) and the
second is to keep constant the total force acting on the plate (in this
case the force per unit area decreases with the deformation). I looked

In Abaqus, *DLOAD element set, Pn, magnitude.

What does "n" in "Pn" mean?

I am doing my master thesis using abaqus in area of structural dynamics. I am in need of help regarded with  how to apply internal pressure, torsional loading , shear loading in buckling of cylindrical shell structural analysis. Please help me in this regard

## Plywood box under pressure on ABAqus

Hello everyone,

I am working right now on a plywood box simply supported by wedges under a uniform pressure of 1 MPa.

The pressure is applicated through a rigid shell part layed on the top of the box ( a surface to surface contact). The bottom of the box is on contact (surface to surface) with the rigid shell wedges (2 on the corner of the box and 1 on the middle).

As a boundary condition, all the DOF's of the wedges are constrained.

## Abaqus- non uniform pressure load in 2D

Hi all,

I am new to Abaqus and I found the problem I unexpectedly cannot solve.... My case is quite simple- I have 2D frame, part of which is under nonuniform pressure distribution (described by linear function). When I create analytical field referring to previously created local CSYS, apply a load in 'static general' with distribution determined in analytical field and try to run a job, i have a message:
