Discovered critical bug in Direct Sparse Solver (DSS) interface that caused invalid assembly of symmetric DSS sparsematrices (SMT_DSS_sym_LDL and SMT_DSS_sym_LL) in many cases.The unsymmetric variant (SMT_DSS_unsym_LU) has been assembled ... [More] correctly.The fixes are already posted to svn repository,Users using distribution version should update manually, by1) replacing  oofemlib/src/dss.C by following file:http://www.oofem.org/svn/tags/rel-1.7/o … /src/dss.C2) replacing  oofemlib/src/dss.h by following file:http://www.oofem.org/svn/tags/rel-1.7/o … /src/dss.h [Less]

Launched project wiki, aimed to promote collaboration between OOFEM users and to provide a knowledge base that can be used and extended by its users. Have a look on it, use it, and contribute to it!

In the last release of oofem (ver 1.7) the DEBUG preprocessor variable has been defined, causing slower (includes bound checked array access) execution even in release version. If you use oofem just for computations, deactivating DEBUG variable (by ... [More] commenting out corresponding line in oofemlib/src/debug.h) and recompiling oofem (make clean, make oofem-release) will give significantly faster execution. [Less]
