Implementation of the embedded beam in solid interface element

Add EmbeddedBeamInterface element to OpenSees:

On windows, you can add EmbeddedBeamInterface.h and EmbeddedBeamInterface.cpp files to the element project in the Visual Studio solution file under UWelements, add a unique tag to the %OpenSees%/SRC/classTags.h (like "#define ELE_TAG_EmbeddedBeamInterface 501") for this element. In the TclElementCommand.cpp do the following:

• First add this line to the beginning of the file where you see a lot of extern commands (around line 130):

extern void *OPS_EmbeddedBeamInterface(void);

• And add this "else if" expression to the  lines further down where you see all these "else if" statements (around line 930):

else if ((strcmp(argv[1], "EmbeddedBeamInterface") == 0)) {  
	void *theEle = OPS_EmbeddedBeamInterface();
	if (theEle != 0)
		theElement = (Element *)theEle;
	else {
		opserr << "tclelementcommand -- unable to create element of type : " << argv[1] << endln;
	    return TCL_ERROR;
	}
}

This should be enough to introduce this element to OpenSees. On linux, besides every change you applied to the files described above, you need to modify %OpenSees%/SRC/element/UWelements/Makefile to include EmbeddedBeamInterface.o, and in %OpenSees%/SRC/ change the Makefile to include "$(FE)/element/UWelements/EmbeddedBeamInterface.o" in the ELE_LIBS variable. You should be able to compile OpenSees applying these modifications!

Add generateInterfacePoints command to OpenSees:

• In the TclModelBuilder.cpp file add the following lines:
  1. Add these somwhere around line 440:

    	// Added by Alborz Ghofrani - UW
    	int
    	TclCommand_GenerateInterfacePoints(ClientData clientData,
    		Tcl_Interp *interp,
    		int argc,
    		TCL_Char **argv);

  2. Add these somewhere around line 660 (Tcl_CreateCommand functions):

   	// Added by Alborz Ghofrani - UW
   	Tcl_CreateCommand(interp, "generateInterfacePoints",
   		TclCommand_GenerateInterfacePoints,
   		(ClientData)NULL, NULL);

  3. Add this somewhere around line 780 (Tcl_DeleteCommand functions):

   	Tcl_DeleteCommand(theInterp, "generateInterfacePoints"); // Added by Alborz Ghofrani - UW

  4. Add these to the end of the file:

   	// Added by Alborz Ghofrani - UW
   	extern int
   	TclCommand_GenerateInterfacePoints(ClientData clientData, Tcl_Interp *interp, int argc,
   		TCL_Char **argv);

• Add files Tcl_generateInterfacePoints.h and .cpp to the element project under UWelements.

If OpenSees compiles without any problems, you should be able to run the test script inside Examples folder and see 24 elements being generated.
