[Nektar-users] Error in apply Dong outflow BCs

26 Feb 2019

      Hi all,

I'm testing out the Robin type BCs for the outflow as given in the user
guide.
Which takes the form of the following

 <R VAR="u" USERDEFINEDTYPE="HOutflow" VALUE="0" PRIMCOEFF="D0/TimeStep"/>
 <R VAR="v" USERDEFINEDTYPE="HOutflow" VALUE="0" PRIMCOEFF="D0/TimeStep"/>
 <R VAR="p" USERDEFINEDTYPE="HOutflow" VALUE="0"
PRIMCOEFF="1.0/(D0*Kinvis)"/>

Upon startup, this gives the error

Fatal   : Level 0 assertion violation
Could not identify matrix type from dimension

I havent come across this error before. Could someone point out what the
error is?
SIncerely,
