…on during assembly and add a trivial equation 1.0e9*x = 0 for those such that the remaining can be solved. Changed: Check matvec.empty() in loop to avoid the need for two loops.
… method be a char and use the value 2 to flag that we want to trace equations with no contribution in the AlgEqSystem method
Removed: Unused methods SAM::initForAssembly() and SAM::getNoElmEquations(). Changed: Use std::accumulate to calculate element size from connectivity. Changed: Don't check return value for methods that will never fail.
be a char to enable forced preassembly in addition to delayed sparsity pattern lock. Force preassembly when element activation functions are used.
be reused by several element blocks instead of duplicating them. Changed: Use null pointer instead of empty ElementBlocks for point grids. Changed: Range-based for loops and x.data() instead of &x.front().
…gument. For exporting grids with active/deactive elements. The node blocks defined for the first step is re-used for all subsequent grids, assuming they also contain the nodes of deactivated elements.
This also includes something which looked like a syntax error not caught by any compiler or static check (when extracting level form string). Minor adjustments for Chebyshev vector/tensor functions such that it does not crash if only one file is specified.

xin the expression will be the element index within the specified patch.This enables the suppresion of equations with no contributions yet.
