expected integer but got "-dir"

[HXHqingdao]

When we used the the twoNodelink in opensees3.3.0,there will display "expected integer but got "-dir"".What should we do?


wipe;
model basic -ndm 2 -ndf 3;
if { [file exists output] == 0 } {
file mkdir output;
}

node 1 0 0 0;
node 2 0 0 0;
node 3 0 0 0;

fix 1 1 1 1;
fix 2 0 1 1;
fix 3 0 1 1;
geomTransf Linear 1;

puts "material";

#uniaxialMaterial ViscousDamper $matTag $K $Cd $alpha <$LGap> < $NM $RelTol $AbsTol $MaxHalf>
uniaxialMaterial ViscousDamper 1 [expr 5400*10000] 8.1 1;
uniaxialMaterial Elastic 2 5400;


puts "element";
element twoNodeLink 1 1 2 -mat 1 -dir 1;
element twoNodeLink 2 1 2 -mat 2 -dir 1;
#inerter eleTag iNode jNode -dir dirs -inertance ib <-orient <x1 x2 x3> y1 y2 y3> <-pDelta Mratios> <-doRayleigh> <-damp cb> <-mass m>
element inerter 3 2 3 -dir 1 -inertance 2;

Looks like there's a parsing error in OpenSees. I'll fix it tomorrow.

Thank you very much. We find that this problem occurs when we input directly, but it can also operate normally when we use the command “source” directly.

[mhscott]

I'm not sure what you mean that it works normally when "sourced"

[mhscott]

OK, I think I know what you mean.

Put a statement at the end of your script, like puts "a". There's some kind of parsing error that's not obvious. It happens with other elements too.
