Hello All.
I have a transient pressure history extracted from results of a third party analysis package at say 1000 discrete points on a flat surface. I'd like to replicate the pressure distribution history on a coincident mesh in /Explicit. The nodal spacing in the FEA mesh is notably finer than the distance between points in the source data - maybe by a factor of four. Any good ideas? This can readily be achieved through a number of tools for a single point in time, but I need to do so for numerous instances.
Note, if I were dealing with a temperature field, I could presumably:
(1) generate a dummy model using the source data points as nodes and assign a temperature history for each point via an amplitude curve,
(2) do a mock (do-nothing) analysis and export the enforced nodel temperatures as output into an odb file, and then
(3) use the INTERPOLATE parameter on *TEMPERATURE in the new model with a large tolerance region.
The approach may not be perfect, but good for a start.
Unfortunately, this trickery cannot be applied with a pressure field as I see it...
Any feedback would be much appreciated.
Thanks. JD
