Code aster is an opensource (free) FEM analysis software targetted to structural, thermal and aucostic analysis. It is available for windows and linux. This software can be used for non-linear analysis and thus is quite useful for engineering studies epscially for academic research. But the sofware is little difficult to use for begineers. I am sharing some introductory videos to get started with this software. You can visit the forum for discussion on your specific problem.

Fortran has come a long way than we had studied in high-school in 19xx. Its now fully supported within Microsoft visual studio. To install Fortran with VS IDE support, ensure the followings:

The method is similar to any other GIS method. The steps are as follows; the main step is highlighted in bold fonts. It is up to you to beautify the map.

Clip it if necessary. This can reduce the computation time.

Reproject the lat/long DEM file to metric base e.g. UTM (this is essential for any area based analysis). Raster>Projection> Wrap

Make sure the projection coordinate used in DEM and your data frame matches.

Fill the projected DEM for any inconsistent data. Processing toolbox>SAGA>Terrain analysis(hydrology)>Fill sinks (wang & liu)

Calculate Strahaler order for the filled raster. This is necessary to know the river lines. The intake location should lie exactly on the river line shown by Strahaler .
Processing toolbox>SAGA>Terrain analysis(channels)>Strahaler order

Delineate the catchment using upslope command. Choose the X,Y coordinate lying on the line calculated by Strahaler . Processing toolbox>SAGA>Terraine analysis>Terrain analysis(hydrology)>Upslope area

Using Raster to vector convert the delineated raster to vector. Raster>Conversion>Raster to vector

Go to attribute table, add new field with formula “area”. The area is calculated in square meters.
