Dynamic Mesh Errors in Flapping wing analysis
5 Attachment(s)
Hi everyone
I m trying to analyze 3D flapping wing. I downloaded UDF from our forum. When i give preview mesh motion it showing " Updating mesh to time 2.90000e-03 (step = 00029)... Wrong " like this it showing for each time step The wing is not moving. Please can you anybody help me for this problem. The following steps i followed: Assigned stationary wall boundary condition for wing in boundary conditions. ( My doubt is whether i have to give any moving wall?) . Others are inlet velocity and pressure outlet. My dynamic mesh settings. smoothing- spring laplace boundary layer with spring factor 0.3. Remeshing parameters i given value from "use default" For dynamic zone I defined Wing as rigid body and keep CG location and orientation default. Here attached screen shot of settings and c file. Please anyone help me on this problem. |
