Hello,

I am trying to model crack propagation using an injection fluid pressure by the XFEM method in ABAQUS.

However, I found in the ABAQUS documentation that in order to apply a concentrated fluid flow in ABAQUS, we have to use *Cflow in the input file.

I am trying to apply concentrated flows to a phantom node located at an element edge between the two specified real corner nodes in an enriched element.

We can do that by the writing the following in the input file :

*CFLOW, PHANTOM=EDGE first corner node number, second corner node number, the magnitude

However, when I tried to import the input file after modifying, I got the following warning:

WARNING: The following keywords/parameters are not yet supported by the input file reader:

---------------------------------------------------------------------------------

*CFLOW

It should be noted that I am trying to apply the injection like the following image:

Thanks
