Hello, I want to ask in this community to see if anyone (espeically LSTC employees) can give me some guidance on the best approach to learn how to properly do fluid structural interaction problems inside LS-Dyna. 

Perhaps we can start with looking at how to do basic CFD problems inside LS-Dyna and I can compare to the Fluent stuff I've done (using simle problems).   From there, I like to ask for some basic materials around CESE.

as far as I can see, this isn't even on the ALH yet and I like to inquire about the best way to learn. 

Thank you

Hello Dennis Chen,

If you are dealing with incompressible fluid flow problems. Please refer to the ICFD solver examples.

https://www.dynaexamples.com/icfd

For compressible fluid flow problems, use the below CESE solver.

Please see the below links for your refrence

Hi Raman, I am very familiar with the dyna-example and the Ansys resources.    I was wondering if there are any resources out there that discuss the use of ansys mesher or the fluent mesher to generate the grid necessary for ICFD or CSES problems or if it can really only be done in LSPP.

I will do more investigation of this topic as well but I am hoping there may be some high level guidance document or reading material that can help me right away. 

also, I again didn't receive a notification haha.   Is this a known issue with the forum?
