It is a step where SimStudio can be really helpful, as closing those gaps would be as easy, as selecting a surface, and pull/push them to extrude them, and snap it to a reference point. This is a step that may require a little more skill in Revit, in order not to touch the references, b ut it would be as simple as editing the right family. Those need to be closed, and we can take the families, and edit them to close them, moving the references, or setting the Fuge distances. For instance, we can redraw a simple extrusion to replace a fully featured window.Ī major thing to take into account would be the fact that we have gaps in Revit. We can assign elements to different levels, and redraw things into those levels. It gives a big advantage to our efforts, as section boxes do not disrupt the model at all, it is a visual tool, but effectively cuts the model according to the needs.Īs drawings can be complex and difficult, Revit has a visual tool, with three level of details defined. We can crop the model to restrict it only to the areas we want to cover.
It is important to notice that if we are doing this from SimStudio, we need to supress the elements, as hiding them (only in SimStudio, not in Revit), will not take them out of the CFD model.Ī major step in model preparation would be to use Section Boxes. We will export only the active view, so in Revit, we can easily duplicate the general view, and create out own customised CFDExport view, with the features we like.Įlements can be easily hidden from the view within Revit. The KEY point in the transition is to take into account that CFD will read only what we actively see in the active view in Revit. This will help a great deal. Launching from SimStudio (CAD tool for simplifying models and launch to CFD-similar features to Fusion) Exporting a neutral format from Revit and bring it direct within CFD Launching direct from Revit (button under Add-In Menu) We do have 3 ways of transferring the model from Revit to CFD:
#Cdf modeling software#
As long as we have a closed volume, the CFD software will void-fill it, to generate a Volume of Control for the simulation. On the other side, we have a CFD model, which needs a closed volume, to define a mesh, to be able to Solve the simulation study. On one side, we do have a Revit model, containing features like model imports, objects, attached or detached parts, worksets, linked materials, MEP parts, etc. I want to summarise the steps recommended for this transition from Revit to CFD.
#Cdf modeling full#
My class at Autodesk University described tools for getting a workflow that take us from a full Revit model into running a CFD study.
The issue of taking architecture, engineering, and construction (AEC) models into simulation software is becoming a hot topic in the industry as companies are starting to include simulation in their Building Information Modeling (BIM) efforts.
