UDF

请教一下大家，就是想输入一个x轴上的加速度随时间变化的曲线，用书上的程序计算不了，用我的程序能计算但结果不对，请问一下是为啥 /*******************************************************************/ /* UDF for specifying an x-momentum source term in a spatially */ /* dependent porous media */ /*******************************************************************/ #include "udf.h" #define C2 100.0 DEFINE_SOURCE(xmom_source, c, t, dS, eqn) { real x[ND_ND]; real con, source; C_CENTROID(x, c, t); con = C2*0.5*C_R(c, t)*x[1]; source = -con*fabs(C_U(c, t))*C_U(c, t); dS[eqn] = -2.*con*fabs(C_U(c, t)); return source; } 计算时就会出现这种情况 ============================================================================== Node 0: Process 8516: Received signal SIGSEGV. ============================================================================== ============================================================================== Node 1: Process 8972: Received signal SIGSEGV. ============================================================================== ============================================================================== Node 2: Process 8036: Received signal SIGSEGV. ============================================================================== ============================================================================== Node 4: Process 1380: Received signal SIGSEGV. ============================================================================== ============================================================================== Node 5: Process 7764: Received signal SIGSEGV. ============================================================================== ============================================================================== Node 6: Process 9360: Received signal SIGSEGV. ============================================================================== ============================================================================== Node 3: Process 7944: Received signal SIGSEGV. ============================================================================== MPI Application rank 0 exited before MPI_Finalize() with status 2 The fl process could not be started. 这是我自己的代码，能计算但感觉没起到什么效果 /****************************************************************** The acceleration in the x-axis direction changes with time *******************************************************************/ #include "udf.h" #define g 9.8 DEFINE_SOURCE(accelaration_source, c, t, dS, eqn) { real x[ND_ND]; real source; real a = RP_Get_Real ("CURRENT_TIME" ); source = -0.125*CURRENT_TIME*g+0.5*g; source=x[0]; dS[eqn] = 0.0; return source; } |

Node 0: Process 4632: Received signal SIGSEGV. ================================================== ============================ ================================================== ============================ Node 1: Process 4996: Received signal SIGSEGV. ================================================== ============================ ================================================== ============================ Node 2: Process 1220: Received signal SIGSEGV. ================================================== ============================ ================================================== ============================ Node 3: Process 1340: Received signal SIGSEGV. The f1 process could not be started. 试过单核计算也没有用，请问您还知道其他解决办法吗？ |
