Frequently Asked Questions (FAQs)

This FAQ page provides a mix of troubleshooting tips, how-to guides, and best practice advice that can help users effectively use the Doriflow Engine and address common issues they may encounter.

​

What should I do if my simulation diverges?

• When a simulation diverges, consider lowering the time step or increasing the resolution to provide more stability. Make sure the Domain size is appropriately configured relative to the fluid particle count, and ensure no extreme values in simulation settings. 

​​

How can I assign Fluid or Solid properties to multiple objects at once?

• To assign Fluid or Solid properties to multiple objects in Blender using Doriflow, first select all the objects you want to assign properties to. Then, open the Doriflow panel, choose the desired property (Fluid or Solid), and click the button. Doriflow will apply the properties to all selected objects simultaneously.

​​

Can I have multiple domains in a single Doriflow simulation?

• Doriflow currently supports only one active domain per simulation to ensure optimal performance and accuracy. If multiple domains are necessary for your project, consider splitting your scene into separate Blender files or using different scenes within a single file, each with its own domain.

​​

Can I use Blender's native built-in Render Animation feature with Doriflow simulations?

• Yes but only when whitewater particles are not included. For simulations involving whitewater particles, it is essential to use the 'Render Final Animation' button provided by Doriflow. This requirement is due to Blender's limitations in updating animated particle emitters. Using the 'Render Final Animation' button ensures that whitewater particles are correctly updated and displayed in each frame.

​​

What are the best practices for ensuring high-quality fluid simulations with Doriflow?

• For optimal results, start with a well-configured domain and ensure your objects are correctly scaled and positioned. We highly recommend using the Doriflow presets for initial setups and adjust simulation parameters such as stiffness, viscosity, and resolution based on the fluid's behavior. Regularly save your work and conduct test simulations with lower settings before final rendering to check the overall fluid dynamics.

​​

How can I optimize simulation performance when using Doriflow?

• To optimize performance, try reducing the particle count or resolution for preliminary tests. Make sure your computer meets the recommended hardware specifications for GPU and memory.

​​

What should I do if I encounter errors during installation or updates of Doriflow?

• If you face installation issues, ensure you are using a compatible version of Blender (version 4.1.1 onwards), and that the Doriflow add-on has been correctly installed without corrupt files. For updates, remove the previous version before installing the new one to avoid conflicts. If problems persist, please contact our support team for direct assistance.
