# SS-T: 3030 Distributed Mass

Apply distributed mass in SimSolid.

## Purpose

- Learn how to apply distrubuted mass bu total area or mass per area.

## Model Description

- DistributedMass.ssp

- Material is set to Steel for all parts.
- Regular connections with 3mm gap and penetration tolerance.
- Modal analysis is pre-defined.

## Open Project

Open the SimSolid project file.

## Option 1: Apply Distributed Mass by Total Mass

Use total mass to apply distributed mass to the model.

This is one of two methods for applying distributed mass. To instead apply using mass per area, see Option 2: Apply Distributed Mass by Mass Per Area.

## Option 2: Apply Distributed Mass by Mass Per Area

Use mass per area to apply distributed mass to the model.

This is one of two methods for applying distributed mass. To instead apply using total mass, see Option 1: Apply Distributed Mass by Total Mass.

## Run Analysis

Solve the analysis.

- In the Project Tree, open the Analysis Workbench.
- Click (Solve).

## Review Results

Plot the displacement contour.

## Compare Results With and Without Distributed Mass

Run the analysis without distributed mass and compare the results.
