SOLIDWORKS Simulation: Increasing Beam Element Mesh Density

by Taran Packer

Beam Element Simulation Study

If you have ever done a 100% beam element Simulation study then you will have run into the fact that when you create a mesh, the dialog box does not show up with meshing options. The beam elements are meshed the exact same way every time. There are cases though when you would want a denser mesh in a beam or mixed element simulation with beam elements in it. How can you do this though if there isn’t a mesh dialogue box to input the mesh parameters that you want for beams?

How to Increase the mesh density of a beam element

Beam elements are one-dimensional mesh elements that simplify and decrease simulation run times while preserving the accuracy of the simulation results. After clicking on the “Create Mesh” button you will most likely see a graphical representation of a beam as you see below.

This beam has 45 mesh elements across its length.

To increase the mesh density of a beam element simply right click “Mesh” then click “Apply Mesh Control.” The Mesh Control dialog box will pop up on the left side of the screen as you see below.

In the “Selected Entities” box, click on all the beams you want to include in the mesh control. These will show up in the box. Next, choose if you want to apply a mesh control to these beams by selecting the number of elements that will be in each or by selecting the element size to be meshed in each. After changing the default settings to the desired units, press the green check mark to accept the mesh control. Now, right click “Mesh” again and then click on “Create Mesh.”

After changing the default settings to the desired units, press the green check mark to accept the mesh control. Finally, right click “Mesh” again and then click on “Create Mesh.” Afterward, the mesh elements chosen in “Mesh Control” dialog box will have a denser mesh as seen below.

The same beam now has 200 mesh elements across its length.  Thanks for reading along!
