For this particular example, we will be using a NACA 4412 airfoil profile. This can be accomplished by importing a curve generated from an airfoil profile plot. The first task is to get the airfoil shape into the SOLIDWORKS environment. To demonstrate this, I have taken advantage of some of the features available in Solidworks and Flow Simulation. SOLIDWORKS Flow Simulation can help reduce the time and effort required to gather data about a potential aerodynamics problem. After running the tests all day, next comes the arduous task of data analysis from the limited data you have collected. If you have ever done any aerodynamic testing, you know that wind tunnels (or time in one) are expensive and requires a lot of pre-testing setup and a lot of data gathering. You can find the load case manager by right clicking the top of the study tree and finding “Load Case Manager” in the drop-down list.SOLIDWORKS Flow Simulation: Lift Up Your Design But instead, we divert to the Load Case Manager! This is where the fun begins! Normally, we would run Here, I specify a draft quality mesh with the standard coarseness settings. Right click on the Mesh node and select “Create I will use basic mesh settings to make the computation Of course, the penultimate step to running a study Top Plane, direction reversed with a magnitude of 9.81 m2. Standard parameters by itself, but make sure that the selected reference is the The “External Loads” node and select “Gravity.” Usually it will fill out Type, magnitude and direction of the force are Live Load 2:įorce with the same parameters as Live Load 1, but with the second rung from YouĬan do this by clicking on the line item and pressing F2. I named it “LIVE LOADġ” to make it easier to distinguish when we get into the load case manager. Might be a good idea to rename the item in the tree, too. Rung in the blue selection box as well, but we must keep them separate for the Remember, it may be tempting to include the other Hit “Reverse Direction” if necessary, to make sure the force is pointing down. The users may be carrying tools.Įnable the “Normal to Plane” Direction button and Let’s lay out the situation: This particular ladder is designed to hold two users on it at the same time (not the best idea in real life for safety reasons other than the structural integrity of the ladder, but we are only considering the structural safety of the ladder in this exercise). The first step is to lay out what the challenge is and what we are looking to analyze. That would arise should we use a geometrically accurate ladder. The ladder is simplified because the focus for this article is loadĬases rather than the intricacies of meshing, different types of bodies etc. The simplified ladder model here to follow along if you wish (SOLIDWORKSĢ015+).
SOLIDWORKSĢ015 was the first year that Load Cases were implemented. In this article, we will explore what it takes to assign load cases for the ladder pictured above.Īrticle will apply to any major version of SOLIDWORKS greater than 2014. The Load Case Manager from within SOLIDWORKS is designed to make assigning these different types of loads and, more importantly, combining these loads easy. Thankfully, SOLIDWORKS Simulation has a way to handle load cases. You could try to reuse the same study and change the values of the forces, but you would lose the history of what the previous values were, as well as being generally tedious.
You could try to duplicate studies, but the clutter would soon become unmanageable. It would be very time consuming to manually consider not just each case, but every combination of the loading cases.
