A pressure load will always stay perpendicular to the surface as it deflects. Split the face to create a new face where you want the force applied. Measure the area of that new face. Divide the Force by the area to compute the applied Pressure.nYou can use a Pressure load in Static Structural or Transient Structural, but in Static Structural, under Analysis Settings, turn on Large Deflection. It is on by default in Transient.n

In addition to peter's comment, you can also use the Follw201 element (recall to flag on large deflection). You have to scope a remote force on where you want to apply the force and promote the remote force to a remote point. Add a command snippet under the remote point and use the following: nET,CID,FOLLW201 !DEFINE THE FOLLWER LOAD ELEMENT nKEYOPT,CID,1,0 !UPDATE THE LOAD DIRECTION nKEYOPT,CID,2,0 ! USE ALL DEGREES OF FREEDOM OF REMOTE POINTESURFnn

Mr. Peter, but since force itself is applied to the scoped geometry in pressure manner by ANSYS itself, so doesn't that mean the force will automatically remain always perpendicular to the scoped geometry? Or we need to first convert the force into pressure and then apply it?n

Force is specified with a direction. That direction does not change as the part deflects. This is useful in the case of force due to the weight of parts at the tip of a cantilever. Gravity always pulls down. You wouldn't want the direction of force to change as the tip bent down. describes a special element to insert (using code) between the force and a remote point to track the motion of the part and allow the force to follow the deformation of the part.nPressure has no direction in the specification. It is defined as a normal force and will update to the new normal as the part deforms with Large Deflection on.nYou must convert the Force to a Pressure to apply it to the face if you don't want to type the code to create a follower force.n
