Hydrostatic pressure load in 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
