Pop quiz! Do you know the answer to this simple PyMAPDL meshing question?

James Derrick

Without checking the documentation, just from reading the following code snippet, how many elements of each material type will be meshed? And why?

from ansys.mapdl.core import launch_mapdl

mapdl = launch_mapdl()
mapdl.clear()
mapdl.prep7()
mapdl.et(1, 'SOLID185')
mapdl.mp("EX", 1, 210e9)   # Young's modulus for steel
mapdl.mp("NUXY", 1, 0.3)
mapdl.mat(1)
mapdl.block(0, 1, 1, 2, 2, 3)
mapdl.mp("EX", 2, 70e9)    # Young's modulus for aluminum
mapdl.mp("NUXY", 2, 0.33)
mapdl.mat(2)
mapdl.block(1, 2, 2, 3, 3, 4)
mapdl.vmesh('ALL')
mapdl.exit()

Will it be...

A - 27 with material type 1 and 27 with material type 2
B - 0 with material type 1 and 54 with material type 2
C - 54 with material type 1 and 27 with material type 2
D - Other...

B. The volumes did not have attributes associated with them so the material ID #2 is active at time of the vmesh. Each block is 1x1x1 which should be meshed with 3 divisions in each direction, so 27 elements per volume.
