SOLIDO upgrade info

Version 3.0w

• New type of boundary condition in RADCON module: transparent material (with conductive and radiative heat transfer), useful for gas cavities of irregular shape (instead of materials of type EQUIMAT).
• New definition of “zoom in” function: a mouse click is required to define the centre of the zoomed view.
• Better feedback (by colour shading) in Image window of current mesh in Grid window and current grid coordinate in Grid Coordinates window.
• Rasterising by swelling: new function to prevent the (partial) loss of thin materials (e.g. metal pins or plates) in the rasterised voxel space.
  This function allows to use less dense grid meshes when thin materials in a slanting position are present in the object geometry.
• Better fitting of grid nodes preferably onto object vertices, then onto object edges and finally onto object surfaces.
  Better solution against the unwanted creation of negative grid cell volumes due to possibly large displacements of nodes through fitting.
• New view factor calculation method, based on automatic surface clustering (based on surface normals and centres) to break down quadratic memory requirement and quadratic calculation time.  Large view factor surfaces are automatically refined to achieve a better precision.
  There is no need anymore to do a preliminary calculation of view factors based on a coarser grid definition.  No view factor factor file is used any more.
• Graphic representation of heat flow densities also in material cutoff planes (through clipping), to visualise heat fluxes inside materials.

Version 2.0w

• Input of STL files.
• CEN rules for automatic calculation of thermal properties.
• Two new types of boundary conditions (borderface BCs, material BCs).
• Separate calculation of view factors, and principle of view factor interpolation.
• Other meshing method with predictable number of nodes.
• Other system solution method (same as in TRISCO), which is now faster and more stable.
• Graphic output: automatic calculation of object contour lines, and clipping against colour regions.
• Text output: colour interface temperatures, view factors.
