File formats¶

Input files¶

The input format is flexible. The parser:

• skips the header lines automatically (lines containing more letters than digits);
• detects the delimiter from the first line: ;, ,, : or, if none is found, any whitespace (spaces or tabs).

Only the column indices must be given, through the ColumnsConfig.

Source files¶

One file per load case, with at least the three coordinates and the value columns. All source files of a folder must share the same coordinates, as the neighbour query is computed only once.

X [m]   Y [m]   Z [m]   Q [W/m3]
0.100   0.200   0.300   3.4e6
...

Destination mesh¶

One file with the IDs, the coordinates and, optionally, the volume or area of the destination points:

• nodes for EM_FORCE;
• element centroids for HEAT_FLUX, HEAT_GEN and HTC.

APDL export scripts¶

The apdl-scripts/ folder contains two macros to export the destination mesh from an ANSYS .cdb file. Edit the variables in the USER INPUTS section, then run the macro in ANSYS Mechanical APDL.

Node_ID,X,Y,Z

columns = ColumnsConfig(id=0, dest_xyz=1, source_xyz=..., value=...)

Element_ID,X,Y,Z,Area,Volume

# volume_area=4 for areas (surface loads), 5 for volumes
columns = ColumnsConfig(id=0, dest_xyz=1, source_xyz=..., value=..., volume_area=5)

Both macros use the same user inputs:

cdb_file = 'CDB_name'                 ! CDB file name without extension
named_selection = 'component_name'    ! Name of the component/named selection
output_file = 'nodes_output'          ! Output CSV file name without extension

Output files¶

export_to_ansys(outdir) writes one interpolated_<name>.txt file per source file, containing APDL commands that can be read with /INPUT. See Load types for the commands written for each load.
