Hello ,
When I use vmult to multiply matrix with vector,I found error information:
Error information:
BOOST_HEADER_DEPRECATED("<boost/core/no_exceptions_support.hpp>")
| ^~~~~~~~~~~~~~~~~~~~~~~
/usr/share/doc/libdeal.ii-doc/examples/cook_membrane3/cook_membrane.cc: In
function ‘int main(int, char**)’:

dealii::BlockVector<double>&)’

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
code:
BlockSparseMatrix<double> output_vector;
SparseDirectUMFPACK A_direct;
A_direct.initialize(solid_3d.tangent_matrix);
A_direct.vmult(output_vector,solid_3d.system_rhs);
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
BlockSparseMatrix<double> is the data type of solid_3d.tangent_matrix
The data type of system_rhs is BlockSparseMatrix<double> .
Could anyone provide any hint or sugesstion?
Thanks in advance!
Best regards
Lance
