creating a new model

Hello,

How can I create a new model and add a Model Category in WEST 2012? What do I need to be careful? I have tried this by using an existing block library and an existing Model Instance in the Model Editor. Even though a new Model Category is added via the Block Library Explorer and it is shown in the Category scrollbar, errors are detected as:
“Missing ASM_New category implementation”
"Error in loading the Block Library. Please check the log file, for more information"

How can I find the log file?

Once again, the procedure you follow sounds correct. I usually do the following:
1) open the BlockLib.xml
2) open the Gujer Matrix editor for the Category which is most similar to the one you plan to create
3) do all the relevant modifications (add components, processes, parameters, ...)
4) close the matrix editor
5) when asked for the category name, provide a different name - otherwise you will overwrite the existing category
This process will create the necessary msl files, add the relevant include statements and create a new Model Instance with the same name as your new Model Category (by default)
6) close and save the BlockLib.xml
