<p>I am encountering an issue with Polyflow in ANSYS Workbench while trying to update the solution. The error message states:<\/p><p>”Update failed for the Solution component in Fluid Flow (Polyflow). Value was either too large or too small for an Int32.”<\/p><p>The project file was originally created by a previous researcher in my lab, and it successfully ran on their system.<br>I am using the same settings and attempting to re-run the project on my computer with ANSYS Workbench, but the solution update fails with the above error message.<br>My system uses ANSYS Student 2024R1, and I am running Workbench with administrator privileges.<\/p><p><br>Here is what I’ve tried so far:<\/p><p>Deleted all files in the …\\dp0\\PFL directory, including .polyflow, .cdata, .lst, and .pfo.<br>Reset the Solution component within Workbench.<br>Tried running the solution update again, but it still failed with the same error.<br>Restarted Workbench in administrator mode and reloaded the project. The issue persisted.<\/p><p>Changed the Mesh Decomposition from Automatic to 256.<br>Enabled GPU acceleration (nvidia) and increased the processor count from 1 to 2.<br>Modified .p3rc configuration, setting MCONTR to 10 from the default 20.<br>Re-ran the solution update, but the error remains unchanged.<\/p><p>Switched the GPU setting to none to test if the error was related to GPU acceleration. The issue persisted.<br>Simplified the mesh settings and reduced mesh complexity, but no change in behavior.<\/p><p>Loaded the original, successful project file directly without any modifications.<br>Reset the Solution and attempted an update. The same error occurs, which suggests that the issue may be specific to my system or ANSYS environment.<\/p><p>Tried running on a system with administrator privileges.<br>Cleared system-level temporary files and ensured there is enough RAM and disk space available.<br>Verified that ANSYS Student limitations (e.g., mesh size, computational resources) were not being exceeded.<\/p><p>The same project successfully ran on the previous researcher’s system, so the issue seems to be specific to my setup.<\/p><p>What could be causing the “Int32” error, and how do I debug it further?<\/p><p>Is it related to Polyflow’s handling of mesh decomposition or boundary condition data?<br>Could it be an issue with my ANSYS Student version limitations or compatibility with this project file?<br>How can I recover the project after deleting files from the dp0\\PFL directory?<\/p><p>The error about missing polyflow.dat seems to prevent me from reloading the project correctly.<br>Are there specific diagnostic tools or logging options I can enable in Polyflow to identify where this error originates?<\/p><p>I’ve tried enabling verbose logging (-debug), but I could not identify the root cause from the .lst file.<\/p><p>ANSYS Version: Student 2024R1.<br>Processor: Intel i7 (8-core).<br>GPU: NVIDIA RTX 3060.<br>RAM: 16 GB.<\/p><p> <\/p><\/p>\n","protected":false},"template":"","class_list":["post-394426","topic","type-topic","status-publish","hentry","topic-tag-ansys-error","topic-tag-error","topic-tag-polyflow"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
