Moving Mesh Fluent
I wanna simulate a cylinder motion in Ansys Fluent but i always get the "negative element"- error.
I got 1 rigit body call "bottom", and the sidewalls call "wall" as deforming body.
The moition works and looks like the picture below :
I'm pretty new to fluent and don't know whats my failture is
I think it looks like my wall move but my domain is stationary and thats the reason why my fluid domain is outside the walls? Correct me if i'm wrong.
I think i got a major issue in my understanding of the moving mesh :-)
Is there any good tutorial for moving mesh?
I think i now the problem but i have no solution
I think I know your mistake.
It looks like your mesh doesn't deform. Your boundary ( piston bottom) simply moves up- and downwards. Is this assumption correct?
I think you have to couple the cylinder wall and the piston bottom to make the same movement. I think the mistake is somethng with your domain nd the moving mesh. Have you looked on re-meshin elemnts and so on?
How can i fix it? Does anybody know?
I'm new to Fluent. Trying to move a piston by applying pressure. How should i do it?
