ccx 2.10

Code: Select all

OS: Ubuntu 16.04.1 LTS
Would you test with this ccx http://packages.ubuntu.com/xenial/calculix-ccx In a fresh xenial install with the ccx from xenial I get an error too if I run the input file

it strange ... if I change the following lines

Code: Select all

*STEP
*CONTROLS, PARAMETERS=TIME INCREMENTATION
4,8,9,200,10,400,,200,,
0.25,0.5,0.75,0.85,,,1.5,
*STATIC, DIRECT
0.1, 1.0
to

Code: Select all

*STEP
*CONTROLS, PARAMETERS=TIME INCREMENTATION
4,8,9,200,10,400,,200,,
0.25,0.5,0.75,0.85,,,1.5,
*STATIC
**0.1, 1.0
after hundreds of iterations I get the 10 results but the max deformation in y is 47 mm not 29 mm. But I do not have a glue what is different.

At the moment I am in contact with the package maintainer of calculix-ccx in ubuntu and debian. Since it seams package related. Only these packages have the problems.

ccx professionals wanted :geek:

Is there someone out there who gets absolute displacement ca 29.77 mm with the file attached?
