Good morning,
*** I am a student who is writing her thesis on a scroll-type expander volumetric and I encountered some problems using the dynamic mesh fluent in package ansys 13. problem: 1) I used to build the tetra mesh from ICEM, correct? or should I use a mesh with hexahedral? 2) the UDF is right? --> #include <udf.h> DEFINE_CG_MOTION(wall_pale_mobili, dt, cg_vel, cg_omega, time, dtime) { Thread *t; face_t f; real freq = 0.13695; real amp = 0.0067; real ampy = -0.0067; real omega; real velx; real vely; omega= 2.0*M_PI*freq; velx = amp*sin(omega*time); vely = ampy*cos(omega*time); cg_vel[0] = velx; /* x-velocity*/ cg_vel[1] = vely; /* y-velocity*/ cg_vel[2] = 0.0; NV_S (cg_omega, =, 0.0); /* no angular motion */ } 3) I used remeshing local cell and 2.5 D. .. what do I need to concentrate? 4) dynamic mesh in the preview, you see only smoothing and remeshing, why? thank you very much |
