Create Solid Mesh Internal Beams in Femap10 Mar, 2014 By: Alastair Robertson
Femap Tips and Tricks: Learn how to set up models that represent rod or beam elements inside solid 3D elements.
Now with the curves and surfaces meshed in separate commands, there will be coincident nodes at the mesh points that will have to be removed. Select Tools > Check > Coincident Nodes… and click the Select All and OK buttons. Clicking the Preview button at this point will show all of the coincident nodes found. Click OK to complete the command.
Now we can create the solid internal mesh. Select Mesh > Geometry > Solid from Elements… and click Select All and OK. In the Automesh Solids dialog, click Options, then in the Solid Meshing Options dialog verify that Delete Surface Elements is checked.
Click OK and OK again to complete the mesh. If a warning message appears requesting to proceed with the mesh, click Yes.
Verifying the interior of a solid model visually can be challenging, but in Femap we can use the grouping function to create a subset of the model that can be blanked off. In this case, we’ll put the corner elements of the block into a group such that when they are blanked off, one of the interior lines of rod elements will be revealed.
Select the Solid icon in the dropdown menu of the View Style icon in the View toolbar. Now we orient the model such that a selection of elements can be made that can reveal a line of the internal rod elements. Select Group Create/Manage… to activate the Group Manager dialog, click New Group… and enter a Title then click OK and Done. Selecting Group > Element > ID… will allow a group of elements to be selected and added into the new group. In the Model Info tree, expand the Groups entity, right-click on the new group that’s just been created, and select Show Active Group.
It can be seen that a contiguous mesh has been created correctly linking the internal rod elements.
