Welcome! - Introduce yourself :)


Hi Feng and welcome to SimScale!

Coupling LBM with a FEM solver is absolutely no problem and can definitely be implemented. Feel free to add your idea in this section along with a description of what cases you want to investigate: Feature Request.

Thanks and happy SimScaling!



I hope SimScale is the best to carry out simulation


Hi @paulnyoike!

Substitute “hope” with “know” and I am with you :wink: Welcome to SimScale! Let us know if you have any questions or ideas that you would like to share with the community.

Happy SimScaling!



i am nana yaw
from ghana
currently in all nations university college offering biomedical engineering
and i have loved to develop an aspirator as my project and i will like to get support.


Hi @naboagye and welcome to SimScale! AAEAAQAAAAAAAAO1AAAAJGRhNTc1ZWI0LTU0NjAtNDlhYS1iMjQzLWEzZDEyMjcwNGVhNQ

We actually have a workshop for biomedical engineering that you can found here in case you want to test some simulations: Biomedical Engineering Workshop.

Happy SimScaling!



Hi, my name is Richard Sauter, I’m from NYC, but I’m living in Bali at present. I’m here to find help in predicting the performance characteristics of a rigid side hull, captured air bubble (CAB) catamaran otherwise referred to as an SES (surface effect ship)

The SES 100B was a scaled down 100’, 100 ton prototype of what was intended to be the fastest 3,000 ton 500’ vessel ever built. It proved everything it was supposed to prove and clearly demonstrated the feasibility of it being scaled up to a 3000 tons , however the feasibility of scaling the SES100B down from 100’ to a 60’ surface effect craft that could do 80knts was not investigated.

In short that’s what my project is focused on doing with scale models and computer simulations

My main objective is to determine the waterjet propulsion power required for this 16m SES to reach a top speed of 80knts

I’m here to find someone who is capable of making that determination from CFD analysis. My own experience is limited to scale models and full size prototype wind tunnel testing.



That looks like a very interesting project that you can definitely investigate some of the objectives you mentioned using our platform. I would have a look at 6 DOF simulation projects as this one right here: Wake Development of a Boat. For the propulsion system we can use the so called AMI or MRF approach. For the speed we can use a result and investigate the momentum/torque. We have to make sure though that a transformation into the local coordinates takes place to get the actual torque from the propulsion system. You can open a new section in the Project Support section and either one of the PowerUsers or someone from the SimScale staff will jump in to help you out.

Looking forward to see some first results on this!
