I have been trying to mesh a solid rectangular geometry having a size of 17 m by 5 m by 0.5 m in lsdyna pre-post with a total of 298 holes of 32 mm diameter of length 450 mm at a spacing of 0.5 m throughout from the top surface of the slab. Started with a element size of 0.5 and 0.25 but prompted an error of hex meshing error: failed to facetize faces. Then with a element size of 0.03 which is less than the hole size it came with a different error of parameterization failed. Can someone suggest what can be causing this error and how can I mesh the geometry.
