Element generation on point clouds
I want to automatically generate a meshed model in APDL. Since my geometry is irregular and I do not want to use a CAD system, it seems the way to go is to generate a list of nodes and then create elements out of them. I have two questions on that:
1) I know I can use EN and ENGEN to create the elements using a pattern. Is there an alternative that does not require a regular pattern (i. e. that just accepts an array of nodes and arranges the elements suitably) ?
2) With EN and EMORE, we can specify up to 16 nodes for an element, which is insufficient for higher order elements like SOLID186. It is possible to create a SOLID186 using the 8 corner nodes, but when displaying the element list, the remaining 12 nodes are assigned the number 0 and are not shown when activating the displaying of nodes under PlotCtrls. Is there a way to get it right?
