Export Geometry in COMSOL
In this blog, we will learn how you can export geometry from comsol Multiphysics. Particularly how you can export specific domains or specific selections from your model to another model. (export domains in comsol, export selective groups in comsol, export complete geometry in comsol )
Building COMSOL Model Geometry
At first you need to build your model lets say you have few blocks used a few other blocks which are overlapping each other and then you have a computer model now you can build all your geometry.
Exporting the model
When you try to export the model you will see that you won't be able to select a particular domain in this case because we have clicked on built all and all the operation inside geometry is included, including the union.
So what you need to do is you need to select the object and then select build all objects so what it will do is, it will build only the objects inside your geometry.
Now you need to go on to export and you will be able to select particular domains from your model to export.
Cumulative Selection for geometry
Now let's say there are hundreds of objects in a model and it is very difficult to select individually so what you can do is you can add selections so select any of your block and then make a group and then add all the blocks in that particular group so in this screenshot you'll see that I have created two groups one box and the other curved.
Advanced Exporting geometry in comsol
Go on to export you will see that there will get options of selecting those elections which you have already made into groups so that you don't have to manually click and select the domains to export.
