CFDEM中添加新的曳力模型

整体的思想与在OpenFOAM中添加新的曳力模型是一致的。

1.在 $CFDEM_SRC_DIR/lagrangian/cfdemParticle/subModels/forceModel/ 路径中创建 myDragForce 文件夹，再在文件夹中创建 myDragForce.C 和 myDragForce.H 两个文件，这两个文件可以直接从其他相似的曳力模型文件中复制过来，再进行相应的修改。

2.对 $CFDEM_SRC_DIR/lagrangian/cfdemParticle/Make/files 文件进行修改，添加 一行$(forceModels)/myDragForce/myDragForce.C 。

3.在 $CFDEM_SRC_DIR/lagrangian/cfdemParticle/ 路径中，执行 wmake ，等待编译完成即可。

POSSIBLE TO RE-COMPILE ONLY MODIFIED FILES IN CFDEM?

 

Submitted by Evan.J on Tue, 03/06/2018 - 19:17

I am modifying some models in CFDEM, and after every change I have to recompile using cfdemCompCFDEMsrc which can take several minutes, and this makes the process of developing a new model very slow.

Is there any way to recompile only the files that have been modified?

I'm a newcomer to this type of programming, so please keep that in mind when answering. Any info or ideas would be helpful!

Thanks,

Evan

HALLO EVAN,

Hallo Evan,
it is of course possible. You must go in src/lagrangian/cfdemParticle folder and type "wmake" in order to compile lagrangian library (all drag force , void fraction models, etc). Only changed files (since last compilation) will be recompiled. The same is possible for each solver separately. For example, if you go in applications/solvers/cfdemSolverPiso and type "wmake", only cfdemSolverPiso will be compiled. Note that you should first compile lagrangian library before solver compilation.

 这里Alexander的意思很明显，在src/lagrangian/cfdemParticle路径下键入“wmake”，只有修改过的文件才会被编译，之前已经编译好的并且没有修改过的文件，则不会被编译。
