Generating elements


Automatic generation of elements is done by clicking on Mesh Mesh generation Generate elements Triangles and quadrangles. To release the mesh, for example, twenty times, in order to obtain optimum angles between the element sides, press Mesh Unbend ….

 


Finished FE-mesh

 

In the above picture, for the sake of clarity, nodes and contours have been hidden (View Node or Contours or press the corresponding buttons).

The markers on the structures were deleted by pressing Structure Edit ( Click on structure) Show Marker or by deactivating the Marker button.

Finally the nodes and elements inside the lake are deleted via Mesh Nodes Delete Area, because the lake is treated as an internal boundary in this model.

The last step in mesh generation is to carry out mesh controls (Mesh Checks…) and eliminating the errors that may have occurred, before step 3: Data assignment is started!

 

The finished mesh and the structure file are available to download on our homepage or was already downloaded (…/Tutorial_bsp_files/Tutorial_2D_bsp_files/schritt2_tutorial.zip). It can be used for further processing.

 

Before the data assignment is started the mesh generator TRIANGLE will be explained.
