What are the methods to define slope in level set models

[alips123]

Hello everyone,
I hope you are well.
I have a quick question. I wanna create some vegetation area models with different slopes to assess the effect of slope on how fire spreads. Besides, there is a house at the end of this vegetation. Till now, from searching and going through FDS user guide, one way to consider slope is to give vegetation surface to specified sloped Geom with specific Verts and Surfs.
But I was wondering if there is another simpler way or line of code to write and add to a model without any slope slope that added part consider slope and its effects. Is there any other simpler way as I wanna assess at least 200 models and can't create Geom and verts and ... 200 times?

Thank you for response.

If you want to run level set in fds with slope you need to define a terrain (either with a terrain GEOM or OBSTs). In order to do this parametrically varying your terrain, you will need to write a script that builds the input files with these objects for the different cases. Look at the file Verification/WUI/LS_ellipse_5ms_30deg.fds for a simple description of a terrain geom with 4 points.
You can also simulate tilted floors changing the gravity vector gvec, but that will not work with level set.
