Hi guys.
I am having much trouble with the midurface-intersect command. This, as I understand it, is the only command available to somewhat automate the arduous task of making sure that orthogonal surfaces will be meshed contiguously, for a plate model.
The issue now, is that 2 out of 5 times, I do not manage to get the surface meshes to actually connect. The NeiNastran folks tell me my geometry is not quite closed, but I wonder to how many decimal places must my gaps be closed before this works?
I know there is a tolerance when checking coincident nodes that I can adjust, but my nodes will only be coincident if I manually define, for each curve at the boundary of 2 surfaces, the number of nodes required. I wouldn't have to do this if the intersect command worked!
At this point, my work would clearly have been complete had I approached this problem with hand calcs.
I have been manually extending, trimming, slicing and generally jerking around with geometry for the past week, unable to create a usable mesh from a step file imported solid model.
Can anyone help? Am I missing something, because if this is all Femap can do, Hypermesh will soon be hearing from me...
