Hi Jacques I have a fully hex mesh. My perception is that for hex elements, modified_a should be used. Please correct me if I'm wrong. syavash On Mon, May 15, 2023 at 3:11 PM Jacques Xing <jacques.xing@kcl.ac.uk> wrote:
Hi Ehsan
I believe that you should use Modified_B basis from GaussRadauMAlpha1Beta0 quadrature. I am also assuming that you are using prism elements for the mesh?

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 syavash
