Subject: [Nektar-users] potential bug with detailed expansion

Dear All,

When I use a "Modfied" type for expansions everything works fine. But if I specify the expansions in detailed mode:

<E COMPOSITE="C[30011]"
BASISTYPE="Modified_A,Modified_A,Modified_A"
NUMMODES="7,7,7" POINTSTYPE="GaussLobattoLegendre,GaussLobattoLegendre,GaussRadauMAlpha1Beta0"
NUMPOINTS="8,8,7"
FIELDS="u,v,w" />
<E COMPOSITE="C[30011]"
BASISTYPE="Modified_A,Modified_A,Modified_A"
NUMMODES="6,6,6"
POINTSTYPE="GaussLobattoLegendre,GaussLobattoLegendre,GaussRadauMAlpha1Beta0"
NUMPOINTS="7,7,6"
FIELDS="p" />

Then I get a bunch of errors:

[xxx518:29773] *** Process received signal ***
[xxx518:29773] Signal: Segmentation fault (11)
[xxx518:29773] Signal code: Address not mapped (1)
[xxx518:29773] Failing at address: 0x27b2000

I have a fully hex mesh.

Could you kindly point out if something is wrong with the way I specify the expansions?

Kind regards
