mesh - 对象不同分区的不同网格大小

Question

我正在使用 ComSol 5.3。我已将我的对象分成两个分区。由于内存问题，我更喜欢为这两个分区设置不同的网格大小。但我不知道该怎么做。下图是我的工作区！

Answer 1

You have already added a "New Tetrahedral" node by right clicking and selecting it from the drop down menu. Now add a second "New Tetrahedral" node by clicking again on the "Mesh 1" node.

Now right click on the "New Tetrahedral 1" node and select "size" from the drop down menu. You can repeat this operation with "New Tetrahedral 2". Select the "Size" node and in the Settings Panel you can change the parameters for the mesh.

To select different domains for each mesh, select "New Tetrahedral 1" and then click on the "Geometric Entity Level" in the Settings panel. Change this to "domain". Now you'll have a window which will show the domains that are part of this mesh. If you do not change "New Tetrahedral 2", it will contain all domains you have not added to other meshes.

Answer 2

是的，这是可能的。您可以通过右键单击“网格”节点或我假设从屏幕顶部的功能区添加不同的尺寸和网格类型。添加新尺寸和可能的新“自由四面体”节点后，您将可以选择将该网格应用于特定域。抱歉没有具体细节，我目前没有 COMSOL 访问权限。但我确实多次为不同的域使用不同的网格。
