# Options and Settings FX-PML separates document options from local application settings. ## Options Tab The **Options** tab is saved with the project file. These values travel with the `.fxpml` project. ![[Images/Options-Tab.png]] General options: - **Author** - **Description** Weather parameters: - **Atmospheric Pressure**, psi - **Ambient Temperature**, degrees F - **Relative Humidity**, from 0 to 1 - **Solar Radiation Flux**, W/m2 Additional costs: - **Debris Removal Cost**, percent - **Other Additional Cost**, percent - **Inflation per Year**, percent - **Inflation Years** Calculation options: - **Include Drift** - **Max Drift Distance**, ft - **Drift Step Size**, ft - **Damage Mapping**, either `Constant` or `Interpolate` Smaller drift step sizes can improve search resolution but increase solve time. ## Settings Tab The **Settings** tab is saved for the local user, not inside the project file. ![[Images/Settings-Tab.png]] Autosave: - **AutoSave** - **AutoSave Duration**, seconds Canvas: - **Grid Spacing** - **Show IDs** - **ID Font Size** - **Snap Angle** Solver: - **Log Level** - **Clear Log On Run** - **Short Pipe Equil. Model**, either `Omega` or `HDI` UI configuration: - **Asset Sorting**, either `Name` or `ID` ## Choosing Damage Mapping Use **Constant** when each location should use the nearest or banded damage value without interpolation. Use **Interpolate** when intermediate values between damage levels are desired. The best choice depends on the methodology used for the study.
