ASI3D8 in openseespy

[xiachunxuDLU]

Hi, everybody,
Message pops: "WARNING element type ASI3D8 is unknown" when running the following code.
Is the ASI3D8 element available in openseespy?

Code: Select all

from openseespywin import *

wipe()
model('basic','-ndm',3,'-ndf',3)
node(1,1,0,0)
node(2,1,1,0)
node(3,0,1,0)
node(4,0,0,0)
node(5,1,0,1)
node(6,1,1,1)
node(7,0,1,1)
node(8,0,0,1)

model('basic','-ndm',3,'-ndf',1)
node(9,1,1,0)
node(10,1,2,0)
node(11,2,0,0)
node(12,1,0,0)
node(13,1,1,1)
node(14,1,2,1)
node(15,2,0,1)
node(16,1,0,1)

element('ASI3D8', 2, *[2,3,6,7], *[9,12,16,13])

while the same code in opensees tcl runs ok.

wipe;
