Implementation of Stokes waves
Stokes waves describe nonlinear, periodic surface gravity waves in inviscid fluids.
More information available in TN-FOU-101830-2.
Convolution integral
The option to introduce forces caused by convolution for hydrodynamic response has been introduced to AquaSim both for beam elements with hydrodynamic loads and membrane elements.
More information available in TN-FOU-101830-4.
Updates to membrane x directions
The definition of directions on Membrane X elements have been updated to be consistent with the right hand convention. Please note that this is a visual change in AquaEdit, not a change in the model.
The local X and Y directions are now consistent with the axis when enabling normals, and the Z axis now show as pointing into the volume as opposed to out from the volume. Please note that this is visual and old models with be consistent and have their normals visually flipped.
The function “Membrane Side” has been introduced to easily visualize which side of a membrane is considered the inside and the outside.
The function “Membrane vertical” has been introduced to turn off the vertical axis visualization to more easily distinguish the direction of the membrane
Updates to handling of “point 3”
We are slowly moving away from using “point 3” as our directionality of beams to defining the direction as a normal on the middle of the element.
This will make the behaviour of the direction of lines more predictable when using various operations. F. ex. when mirroring a line across an axis, the normal will also be mirrored to create a perfect mirror image. The same has been applied to rotation and moving lines / nodes.
A bug when using extrude and duplicate has been fixed with the introduction of the normal behaviour.
Changes to how max out files are generated
Previously, the max out process copied all PFAT files to a sub-folder to complete processing. The requirement for the subfolder has been removed and a (analysis name)_maxout.bat file is generated. This file will complete the neccessary steps to create the max-out file, either manually - if the option “create max out file” is not enabled - or automatically. This file will now also be automatically run (depending on if the forementioned option is on) on analysies with “export groups” enabled.
This fixes .obj files not being included in the resulting maxout file, and reduces clutter.
Example maxout.bat file
@ECHO OFF
REM Creating max out
avspostproc.exe "run01pfat.avz" "run02pfat.avz" "run03pfat.avz" -out "run_max_out.avs" -mode max
avspack.exe -join "run_max_out.avs" "run.xml"
ECHO Creating max out file
del "run_max_out.avs"
Example during group runs
@ECHO OFF
(
START call "run_g1.bat"
START call "run_g2.bat"
START call "run_g3.bat"
) | set /P "="
"run_maxout.bat"
exit
