The considered mass scaling preserves the element translational inertia, while it modifies the. If the dt parameter is omitted, all variable mass scaling definitions from previous steps are. Rough measures for large models based on number of variables. Mass scaling can also be accomplished by altering the density. As abaqus user manual suggested, the mass scaling is only applied to the. For analyses using variable mass scaling, the total mass added to achieve a given stable time increment will be less with the improved estimate.
I m using mass scaling to fixed increment and plotting the dmass variable to look. These regions usually are meshed to smaller sizes because. Im using mass scaling to fixed increment and plotting the dmass variable to look. You can define a desired elementbyelement stable time increment for an element set for fixed or variable mass scaling. Pressurized fuel tank with variable shell thickness. As abaqus user manual suggested, the mass scaling is only applied to the elements that are critical in determining the computational time. How does the mass scaling reduce the computational cost during. How does the mass scaling reduce the computational cost. If the dt parameter is omitted, all variable mass scaling definitions from previous steps. Selective mass scaling for distorted solidshell elements in. How can i speed up the running time of my model with.
