Hi everyone, I'm trying to convert a scaled Gait2354 model from OpenSim (.osim) to the Hyfydy format (.hfd). I'm new to Hyfydy and could use some guidance on the process. Specifically, I'm wondering: Has anyone successfully converted and used the Gait2354 model in Hyfydy? If so, could you share your...

Thank you for your answer! Your guide to scaling in SCONE is correct, but I'm using OpenSim for both scaling and refining the model with RRA for forward dynamics analysis. I noticed the H1922 model is similar to gait2354, and I haven't found other models that closely match its structure and my neede...

Thank you for your reply To clarify my question, I'm looking for a 3D OpenSim model that would be suitable for forward dynamic simulations of walking and running. I'm planning to scale the chosen model using gait data of walking and running and then implement it in the Hyfydy format. Specifically, I...

Hi everyone, I am working with the scaled RajagopalLaiUhlrich2023 model and an improved RRA output model. I'm looking for guidance on how to represent these models in the Hyfydy format. Specifically, I would appreciate any of the following: Step-by-step instructions for converting these specific mod...

Thank you for the suggestion! I've encountered an issue with the addTableMetaDataString function when writing MOT files. It seems the function adds metadata strings to the file based on alphabetical order, which prevents me from placing nColumns before nRows. This results in OpenSim being unable to ...

Hi everyone, I'm working on a project using OpenSim 4.5 and encountered an issue related to applying ground reaction forces (GRF) to a model. While following the OpenSim tutorial, I observed specific messages in the OpenSim console related to GRF application that are not present in my own setup. The...

Hi Aaron, Thanks for your reply. I've noticed a difference in the results compared to the tutorial. The tutorial shows the following messages in the OpenSim console: ExternalLoades: external_loads_model_kinematics_file option is not supported anymore. Results may change. ExternalLoads 'grf_walk' was...

Hi everyone, I'm working on a gait analysis project using data from five force plates and plan to perform inverse dynamics and residual reduction analysis (RRA) in OpenSim. I'm unsure about the best way to handle the force plate data and would appreciate your guidance: Option 1: Separate Force Plate...

Thank you for the suggestion! To help me understand, could you please share some detailed instructions or examples related to my use case? Also, I'm working on verifying joint angles I obtained through inverse kinematics in OpenSim. I'd like to verify these angles using forward kinematics within Ope...

Hi everyone, I have a set of absolute segment angles obtained from IMU sensors, and I need to compute the marker locations using forward kinematics (FK). Could anyone guide me on how to achieve this? Is there a specific function in OpenSim that can be used for this purpose? Any detailed instructions...
