spacing to top and lower layers of shell. The coor_refine=0.1,0.15,0.1,0.2 parameters specify the radius fraction of the bottom layer [0], the fraction of the nodes in this layer [1], the top layer fraction [2], and the top layer node fraction [3]. I.e. the defaults will put 15% of all nz nodes into the 10% lower layer, 20% in the top 10% upper layer, and the rest in between. - renamed gzipped output version with sub-directory storage ascii-gz - built in restart facilities for temperature and tracers when using ascii-gz I/O with vtkio != 2 - added a composition viscosity function, CDEPV, based on two tracer flavors - for this to work, I had to move viscosity_input() *behind* tic_input() and tracer_input() in instructions - added tracer_enriched option for internal heating. If tracer = on and tracer_enriched = on, will reader Q0_enriched and vary the element heat production between Q0 for C = 0 and Q0_enriched for C = 1. I.e. this only works if C varies between 0 and 1. - added an option to write from all processros to a single VTK file, if ascii-gz is activated, and vtkio = 2. The VTK output is of the "legacy", serial, single-file type, and requires that all processors see the same filesystem. This will lead to a bottleneck for large # of CPU computations as each processor has to wait til the previous is done. More efficient I/O should be possible by using the distributed storage version of VTK, but I have no clue how this works. Anyone?
