From 0cf1404db0d089d8f5adbdbb9e989a1bcb43fcc2 Mon Sep 17 00:00:00 2001 From: Philip Eisenlohr Date: Thu, 27 Jan 2011 14:32:29 +0000 Subject: [PATCH] changed from element 117 (hexahedral with reduced integration) to element 7 (hexahedral with full integration). one-IP elements give trouble in the ping-pong scheme by being frequently/always outdated. this is likely connected to their finite element technology such that even high stiffness values do not prevent the solver from altering displacements in subsequent cycles. remedy is to go for full integration combined with /elementhomogeneous/ phase... --- processing/pre/mentat_spectralBox | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/processing/pre/mentat_spectralBox b/processing/pre/mentat_spectralBox index a23fbee87..7b1f072d2 100755 --- a/processing/pre/mentat_spectralBox +++ b/processing/pre/mentat_spectralBox @@ -105,7 +105,7 @@ def material(): "*add_mater_elements", "all_existing", "*geometry_type mech_three_solid", - "*geometry_option red_integ_capacity:on", +# "*geometry_option red_integ_capacity:on", # see below: reduced integration with one IP gave trouble being always OUTDATED...
