Still standing water expand strongly

Kyushu_panda

April 2021 in DualSPHysics v5.0

Hello!

I had a 2D case in which a non-Newtonian fluid slides into a stationary Newtonian fluid.But I noticed a strong expansion in still water.At first I thought the expansion was caused by the sliding body crashing into the still water.However, when I tried to fill only the static Newtonian fluid without setting the non-Newtonian fluid sliding body in the calculation example,

I found that the static water still showed strong expansion phenomenon. I am not understanding why it happens.

Has anyone ever had a similar problem in the simulation？

Thanks !

Hi Kyushu_panda
I am not sure what you are trying to simulate. I might need to have a quick look at your xml file.
Please send it over through usual channels.
Thanks
George
