BACK TO MAIN MENU   To calculate weights, you must have previously meshed a model. The mesh name appears on the project tree on the left side of the screen, as shown below:   To perform a weight calculation, highlight the mesh name and select Mesh Weights. The following window will appear: Note: To obtain

BACK TO MAIN MENU   An Iso-Surface is a three-dimensional surface inside the casting model that displays where certain output data has a particular value. This means that you are plotting ONE VALUE of the selected type of output data. To plot an Iso-Surface, first double-click on the Simulation icon on the project tree, in

BACK TO MAIN MENU   Cut Plane plotting involves showing simulation results on a 2D plane cut through the casting. To plot a Cut Plane, first double-click on the Simulation icon on the project tree, in the SOLIDCast main screen. Now, at the menu bar select Simulation… Plot Cut Plane. A window similar to the

BACK TO MAIN MENU   CastPic is a function that can create a detailed, three-dimensional image of the casting with result data plotted onto the image as a range of colors. This function can show the whole casting or section the image to show internal details in the casting. To make a CastPic image, first

BACK TO MAIN MENU   Solidification Time shows the time, in minutes, for each part of the casting to become COMPLETELY solid, i.e., to cool to the Solidus Point. Viewing a plot of Solidification Time shows the progress of solidification through the casting. This can help to locate isolated areas of molten metal within the

BACK TO MAIN MENU   When castings are made by the investment casting or permanent mold process, a considerable amount of heat is lost from the surface of the hot shell or die in the form of radiation. The amount of radiant heat loss varies according to whether various surfaces face the ambient surroundings or

BACK TO MAIN MENU   To run a simulation, you must have previously created a mesh. The mesh name will appear on the project tree on the left side of the SOLIDCast main screen. Highlight this mesh name, then from the menu bar select Mesh… Start Simulation. The following window will appear: You can select

BACK TO MAIN MENU   Critical Fraction Solid Time records the time, in minutes, for each part of the casting to reach the Critical Fraction Solid Point. This is the point at which the alloy is solid enough that liquid feed metal can no longer flow. Therefore, for judging directionality of solidification, and whether any

BACK TO MAIN MENU   The Material Density Function is the result of a calculation in which the contraction of the casting, and resulting flow of liquid feed metal, is taken into account during solidification. Areas that have metal removed due to feeding liquid metal to other areas of the casting will show up as

BACK TO MAIN MENU   Temperature Gradient is a measure of how much change in temperature there is as you go from point to point within a casting. A high temperature gradient means that there is a large temperature change within a short distance within the casting. A low temperature gradient means a small change

BACK TO MAIN MENU   Cooling Rate is a measure of how quickly a casting is cooling down, in C per minute, measured at each point in the casting as that point hits the Niyama Point on the cooling curve. Cooling Rate can be an indication of material quality. Areas of the casting that cool

BACK TO MAIN MENU   The Niyama Criterion is a function based on Temperature Gradient and Cooling Rate. The criterion was developed by Dr. Niyama, a Japanese researcher studying shrinkage prediction in steel. Niyama found that the Temperature Gradient divided by the square root of the Cooling Rate corresponded to the presence of shrinkage porosity

BACK TO MAIN MENU   If two shapes in a model overlap and are made of different materials, then the system needs to know which material should occupy that overlap region when the model is meshed. This is accomplished through the use of  Priority Numbers. Priority Numbers: Are assigned to EACH INDIVIDUAL SHAPE in a

BACK TO MAIN MENU   Hot Spot plotting is a function in SOLIDCast that locates thermal centers or hot spots within the casting by comparing solidification times or critical fraction solid times of points within local areas. The range of values is always 0 to 10, and generally the value plotted is around 1.1 or

BACK TO MAIN MENU   Custom Criterion is a function that allows you to plot data from standalone programs in SOLIDCast. These programs are available from Finite Solutions, Inc. Or, you can develop custom criteria functions using one of the stand-alone utilities described in Unit 46. One custom function calculates the FCC Criterion, which was
