Large Assembly Design Tools Create and manage extremely large designs and work in either detailed or simplified modesĬonceptual Design SOLIDWORKS conceptual design capabilities enable you work with all types of conceptual design data, including sketches, images, Adobe® Illustrator® files, 3D scan data, and existing 3D and 2D CAD data.
SOLIDWORKS FLOW SIMULATION MATRIX UPDATE
In the next portion of this post, I will be discussing solution adaptive mesh settings.3D Solid Modeling Create 3D parts with complex geometries, assemblies, and associated drawings drawings automatically update with part and assembly changes, to keep all your design data up to date That is the basic settings for the initial mesh. Otherwise, the entire global domain, or local domain if you are using the local initial mesh settings, is used. Turning on the bottom two options for minimum and maximum height of narrow channels limits what constitutes a narrow channel. The process stops when either setting is hit.
SOLIDWORKS FLOW SIMULATION MATRIX SOFTWARE
It allows an input of the minimum number of cells you desire, as well as a refinement level of how many times you will allow the software to split the cells in an attempt to achieve that. The Narrow Channels tab deals with areas where flow conditions occur in small gaps. Tell the software how many times you want it to split each cell type before starting its run. In the refining cells tab, the options are simple. If this discretization error is large, then splitting cells makes it more accurate. If you think of a quarter circle in a single cell, its solid representation is actually going to be a triangle made by the edges of the cell and a line connecting the two points the quarter circle intersects with the cell edges. Tolerance refinement level: Used to make sure the deviation of the discretization from the actual surface geometry is not so large to cause issues.

Think of features that are thin, short, etc.Ĭurvature refinement level: Looks at surfaces with too much curvature and refines them as many times as allowed by what you have set This is done to minimize errors from bad discretization of a curved surface by a rectangular/cubic cell. Small solid features refinement level: Allows refinement around features in which one or more dimensions is small compared to other features around it. For now, we’ll move on to settings of the initial mesh. We’ll be talking more about that in a later post in this series. Second, solution adaptive meshing only refines cells that need it as the solution progresses keeps things efficient. First, it’s unlikely all cells from each refinement will ever continue to be refined, typically making the mesh much less resource intensive then 8^8 cells from one cell would indicate. And, that’s just from one cell out of the basic mesh! There can be thousands or millions in the basic mesh! This is why the settings exist, so the software can sort out what needs refinement and what doesn’t – otherwise you would never finish an analysis in any reasonable timeframe. That means that a single cell that would normally take about 10 kB of RAM to store would now produce about 16GB of RAM needed if all cells created by refinements were continually refined up to the max as well. You can imagine how many cells would be created if every cell was refined eight times. Level 7 and Level 8: Uncolored because they are too small to make out.If all the cells combine to make one starting cell, then the following is a table to put the different refinement levels in the image in perspective: The image below shows multiple refinement levels. Each cube splitting into 8 equal cubes represents one level. The refinement level is the maximum amount of times a cube that represents a cell can be split. This post will be a discussion of those settings.īefore we discuss the actual settings, let’s talk about what all the level settings are since we see it multiple times in Small solid features refinement level, Curvature refinement level, and Tolerance refinement level. The software starts with the basic mesh, then refines area with certain geometrical features based on the different settings in the software. The initial mesh of a Flow Simulation is the first mesh used for performing actual calculations. Now we’re going to take a closer look at an initial mesh. We’re in Part 3 of our SOLIDWORKS Flow Simulation series! So far we’ve covered the basics and the stages and we took a closer look at a basic mesh.
