read the boundary conditions

read the frequency curves and the data for post process (not be used)

read mesh as the mesh definition allows jumps in the indices of elements and node we alway need reference vectors for matrix entry to the reference nu

the main program for seting up the equation system

store the boundary conditions

update the admittance boundary conditions and the incident waves by using the curves describing their dependance on the frequency

write the job parameters into the output file

compute and write the sound pressure, velocity and energy intensities at nodes of the evaluation mesh (i. e. the internal points)

compute and write the results at the boundary

check if the normalvectors point in the same direction

Calculate center and area of receiver elements in reciprocal simulation.

Check if an evaluation grid contains an isolated node, i.e., a node that is not contained in any element. Mesh2HRTF can not handle this.

Check if evaluation grid exists. Raises ------ ValueError if the folder or neccessary files do not exist.

Check the evaluation grids for isolated nodes, duplicated node IDs, and overlapping node IDs with the Reference mesh

Calculate list of frequencies. Returns ------- frequencies: list list that holds the frequencies in Hz that are calculated.
