I want to run a simulation of a ducted underwater propeller. I defined a solid region(MRF) to enclose the blades and imported the model onto simscale, After the mesh is generated when i check my geometry, the blades enclosed within the MRF region are missing altogether. How do I fix this ?
Can you make sure that there are no intersections between the MRF zone you defined and other parts of your model? Let’s see if this has an effect on the mesh.
I tried again with another model with a more refined enclosure to define the rotating zone but still when I mesh, the blade geometry is missing. Any suggestions as to how to fix this?
Hi @Targaryen, you havn’t actually defined the surface refinement to create a cell zone. To do this create a new surface refinement, select the MRF geometry and ‘true’ create cell zone. you can actually see the zone hasnt been created at all by clipping the mesh:
I am new to Simscale. I am trying to simulate a single turbine blade under sea water. I created the blade, MRF and boundary box (fluid domain) in Catia then I imported it as .step file in Simscale, I got three solid zone after importing the geometry. One is Blade with faces, MRF with faces and boundary box with faces. But I couldn’t able to import the geometry to get single solid volume without any faces for MRF. Could anyone tell me how I can define the MRF as a single solid volume zone?
Is there any tutorial to learn how to import or create MRF zone in Simscale? This is link of my project
How to create a qualtiy mesh in blade tip? If you see my mesh in blade tip isn’t have good quality.
You can also just import the enclosed turbine blade and let the mesher take care of the bounding box. You can find a tutorial right here: MRF - Centrifugal Pump Tutorial.
I followed the tutorial. In the tutorial I can able to create the " Region Refinement" and I can able to select the rotating zone as a solid volume (It’s has three faces).
But in my project SimScale I couldn’t able to create the " Region Refinement" volume. I couldn’t able to understand why I can’t able to create the " Region Refinement". Is there any open in rotating zone or any mistake in importing the geometry?
Sorry for the late follow up!! Did you solve the issue by yourself or do you still need help on this? Please let me know so we can finish this case for you as fast as possible!
Feel free to re-upload the geometry without the box, let the mesher create the box. Once that is done we may continue with the setup. Share the project once you have uploaded the project without the box. Thanks and cheers!
