How to represent the stress of irregular waves on objects in AQWA in a cloud map. It seems to use APDL. But how to import apdl I don't understand  

[Yu Bi]

Hi, you can consider using the Hydrodynamics Pressure Add-on to load the pressure calculated in Aqwa to Static Structural and do a stress analysis in Static Structure. More details about the Hydrodynamics Pressure Add-on can be found in Aqwa User's Manual Section 8.1. Also, if you have access to Ansys Learning Hub, in Aqwa training materials, there are lecture and workshop slides on this subject. 

Hope this helps.

Thank you, I understand, but I want to produce shear with the result of the time domain, but the static structure tells me that there is no pressure result file for the production time domain, and where is this result file generated? Not found

Hi, please first make sure you can view the Time Domain Pressure results in the Aqwa Hydrodynamic Response analysis. The results that will be transferred to Static Structural are there. Then once the link has been created correctly between the Hydrodynamic Diffraction/time domain Hydrodynamic Response and Static Structural systems, it is always necessary to right-click the Hydrodynamic Solution cell and select Update. This operation manages the transfer of data files between the analyses. Note when some hydrodynamic data has already been imported into the Static Structural system, and the Hydrodynamic Solution is subsequently updated, the Static Structural Setup cell must be refreshed. In Mechanical, it is essential to click the Hydrodynamic Pressure object after this Refresh operation to utilize the new hydrodynamic data.

Hello, there is no pressure result in the time response option of my aqwa2021R1 version that cannot be imported into the static structure. How to solve this problem to generate the stress diagram of the structure in a static structure. There is an import result file option in the static structure, but the file suffix is required to be. rst or. rth. Can AQWA generate the corresponding file? Can I obtain a time-domain stress cloud map by uploading the result file

Why does my static structure report this error, my structure is also an English name

[Yu Bi]

Hi, again, this is usually either due to HD Analysis has not been connected to Static Structure correctly, or the solution sell of HD has not been updated and Static Structural cell has not been refreshed.

Why do static structures report errors in additional damping in AQWA

[1317794602]

How the quality in the static structure is inconsistent with the quality in AQWA. How to modify it to match the quality in AQWA

How to turn off this effect when the picture protrudes  in static structure 。 thanks

[Yu Bi]

The forces due to the additional damping will not be transferred to static structural, however, the structure acceleration which will be transferred to static structural to calculate the dynamic forces is calculated with the effect of the additional damping. This is the reason for the warning message.

Material properties and geometry decide the mass of the bodies in Static Structural. 

Not quite understand what is happening in the picture, however, if there is no option in the UI to turn it off, then it means it cannot be turned off. Please check the User's Manual for more information.
