Yeah; a string like "sin(t)*sin(x),cos(t)*cos(y),sin(t)*cos(z)" would be a space-time-dependent definition of a field of three (comma-separated) output variables. I'm probably going to be too lazy to implement *named* output variables, though, so you'd have to be careful not to write equations for u,v,p if your system variables are really p,u,v. And this would be useful for material properties, forcing functions, etc. too. If opinions are positive: does anyone want to get really crazy and put it in contrib/ ? It's MIT licensed, and I've got to build it by hand for myself anyway since the Debian package is way out of date. --- Roy ------------------------------------------------------------------------------ Try before you buy = See our experts in action!
