Example with analytical solution
greetings everyone!
Are there any examples with analytical solutions in this program?
(such as Taylor-Green Vortex)

There is an example with Poiseuille flow, if that is what you mean?
I also believe that the Taylor-Green Vortex has been simulated in a few different SPH papers, but I don't think there is an easy way to do it directly inside of DualSPHyiscs, without altering the code - I might be wrong though!
Kind regards
Thanks for your guidance!
I tried to solve the Taylor-Green Vortex problem with Dualsphysics, but when I set the gravity to zero, it gives an error.
Kind regards.
What was the error? It could simply be that you have to specify a speed of sound directly, which is a common error when gz has been set to zero.
Kind regards
Dedicated to you
Please follow the example in DualSPHysics_v5.0\examples\main\03_MovingSquare where we have imposed the value of cteB:
<b value="1.1200e+05" auto="false" />
Otherwise with gravity = 0 then cteB=0

Thank you very much for your guidance and kindness
Exactly as @Alex said, just to show you the formula as well:
So you should not set b to anything random, but here you have a formula of how to calculate it.
Kind regards
Thank you very much for making this clear to me
