does any one of you know why I am getting the follwing error?
[error] Mesh generation has failed. Specific details may be found in Modeler>Model Analysis>Show Analysis Dialog>Last Simulation Mesh. (10:51 AM May 19, 2008)
[error] Simulation completed with execution error on server: Local Machine. (10:51 AM May 19, 2008)
when I validate I don't get any warning however when I run I get the above error.
There is probably something wrong with your model. I have occasionally "fixed" this type of problem by redrawing the model (from scratch). Validate does not always catch all the problems.
If the model isn't too complicated that may be the easiest solution. Another technique is to look carefully at the model at a high magnification to see if there are spikes or stray edges that do not belong.
please make sure the maximum mesh length you have given is proper otherwise this error occur. Also as akedar says the region might overlapping. Check the corners and the intersection of your models.
