I'm using Pro-Mechanica at present for the modelling of water storage
tanks, as part of our engineering department's work on low-cost
domestic rainwater harvesting.
Having made solid models of possible tank designs, I now want to apply
suitable constraints for the FEA analysis. Ideally I would like to be
able to constrain the base of the tank such that any displacement
downwards would generate a resistive force that increased with
displacement (probably linearly), but that any displacement upwards
would not generate any resistive external force.
I seem to remember the old Pro-Engineer version of mechanica having a
spring constraint option in the constraint dialogue box, but in
Wildfire the options are now free, constrained, or specified
Does anyone have any advice?
