Comparison between SLIQ2D-DOS and SLIQ2D-Windows
...
In SLIQ2D-Windows only the value of the tangent angle is available in the output. The other parameters (such as Lambda, Ko, the normal stress p and the deviatoric stress q) are not saved and can only be red on the screen, making the comparison difficult. That's why only the tangent angle at which the point is instable is compared between SLIQ2D-DOS and SLIQ2D-Windows.h7. is compared between SLIQ2D-DOS and SLIQ2D-Windows.
The relative error show in the table below come from some difference in the automatical generation of the variable values of the tangent angle used by both programs:
- SLIQ2D-DOS uses slopes from 1:20 until 1:1.5
- SLIQ2D-Windows uses 2 extra slopes compared to SLIQ2D-DOS: 1:1.4 and 1:1.3
