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** Georeferencing: - **True North**, declination between the canvas +Y axis and true north, deg - **Origin X**, X location of the georeferenced point, ft - **Origin Y**, Y location of the georeferenced point, ft - **Longitude of origin**, longitude of the Origin X location, deg - **Latitude of origin**, latitude of the Origin Y location, deg The georeferencing fields tie the document's local XY world (in feet) to real-world geographic coordinates. A single known point anchors the two systems: its local position is (**Origin X**, **Origin Y**) and its geographic position is (**Longitude of origin**, **Latitude of origin**). The local +Y axis is rotated from true north by the **True North** declination. With these set, FX-PML can convert any canvas location to and from longitude/latitude, projecting distances and bearings onto the WGS-84 ellipsoid. Weather parameters: - **Atmospheric Pressure**, psi - **Ambient Temperature**, degrees F - **Relative Humidity**, from 0 to 1 - **Solar Radiation Flux**, W/m2 - **Wind Speed**, mph Additional costs: - **Debris Removal Cost**, percent - **Other Additional Cost**, percent - **Inflation per Year**, percent - **Inflation Years** Additional costs are calculated from the total property damage before additional costs: - Debris removal cost = Total property damage * Debris Removal Cost / 100 - Other additional costs = Total property damage * Other Additional Cost / 100 - Inflation costs = Total property damage * ((1 + Inflation per Year / 100) ^ Inflation Years - 1) - Total loss = Total property damage + Debris removal + Other additional costs + Inflation costs Discharge calculation options: - **Droplet Method**, one of `Simple Rainout`, `Original CCPS`, `Modified CCPS`, or `DNV droplet JIP` - **Expansion Method**, one of `Isentropic`, `Momentum`, or `Closest to Initial` - **Velocity Capping Method**, either `Fixed Velocity` or `Sonic Velocity` - **Max Release Velocity**, ft/s The **Droplet Method** field selects the model used to calculate liquid release atomization and rainout. The **Expansion Method** field selects the model used to expand the release to ambient pressure for gas and liquid sources. The **Velocity Capping Method** field allows you to choose the method used to set an upper limit on the calculated discharge velocity. If you choose **Sonic Velocity**, the upper limit is set by the sonic velocity for vapor under the discharge conditions. If you choose **Fixed Velocity**, the upper limit is set by the value in the **Max Release Velocity** field. Damage calculation options: - **Include Drift** - **Max Drift Distance**, ft - **Drift Step Size**, ft - **Damage Mapping**, either `Constant` or `Interpolate` **Constant** treats the damage contours as bands. A location between two damage-level radii receives the outer, lower damage percentage for that band. **Interpolate** linearly blends the damage percentage between adjacent damage-level radii, giving intermediate values between the defined damage levels. For both methods, locations inside the innermost contour receive the innermost damage percentage, and locations outside the outermost contour receive zero damage. 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`
