Problem setting C_MU_T with DEFINE_ADJUST

Hi,
i´m trying to change turbulent viscosity (for an extension of the ke-model; DEFINE_TURBULENT_VISCOSITY is not accessible in Eulerian multiphase) in the Eulerian model using UDF. I'm using a DEFINE_ADJUST , but I get an error message when I compile my code. The compiler tells me: error C2106: '=' :left operand must be l-value DEFINE_ADJUST(turb_adjust, d) { Thread *t; cell_t c; thread_loop_c (t,d) { if (FLUID_THREAD_P(t)) { begin_c_loop_all (c,t) { C_MU_T(c,t) = 1; /*C_MU_L works!*/ } end_c_loop_all (c,t) } } } Same error occurs for C_MU_EFF. But if i use the C_MU_L no problem (or C_R(c,t))! So where´s the problem with the eddy viscosity? I hope someone can help me out off this! Thanks. Andy |

hello. i met the question similar with yours. i used the DEFINE_ADJUST to adjust the viscosity of the material. However, when the "C_MU_L" occurs in my UDF, it will make mistake as followings:
Error [cortex] [time 7/30/14 15:49:6] FLUENT received fatal signal (ACCESS_VIOLATION) 1. Note exact events leading to error. 2. Save case/data under new name. 3. Exit program and restart to continue. 4. Report error to your distributor. No matter how simple the UDF is, if the "C_MU_L= " occur, the error will appear. do you know the reason why it happens? |

I think the value of C_MU_T(c,t) should be return real value. |
