Femap

This is the processes to define a hydrostatic pressure load in Femap

Create a Coordinate system at the top of the fluid level. Model->Coord Sys.

In my example I am defining Y in the direction of the depth. Zero Y will represent the top fluid level.

Create an equation data surface. Tools->Data Surface Editor

Enter in the following equation.

Link to the Correct coordinate system.

Define the equation as listed above. !y calls the distance in Y in the coordinate system specified.

Density = 0.036 lbm/in^3

Gravity= 386 in/s^2

Height=Variable in

Be careful with units. Make sure you are using consistent units. To get consistent units in my case I needed to divide by 386 in / s^2

Results in lbf/in^2
