# MPTE Model \[MPTE]

The MPTE Model is designed to generate multiple models using a single row of data. The goal is to create a reference model using the inputs under the **Pile and Soil Molde**, and **Analysis Settings** tabs, as well as other workflow objects. Therefore, creating only one row of data is sufficient to perform the analysis needed to find the critical length of the pile.

Based on the desired trial embedments, OpenBrIM creates multiple models and displays them all within the same project. This allows all trial lengths to be analyzed simultaneously, thereby reducing the overall analysis time.

### Pile and Soil Model:

**Top Elevation of the Pile:** Enter the reference location of the model. All other elevation values should be entered based on this value.

**Pile Length/Section:**

* **Section Length(Starts at bottom of footing):** The top of the pile, which begins at the bottom of the footing, serves as the starting point for section definition. Users can define multiple rows to create sections with varying characteristics. The total length of the pile is calculated by summing the lengths of each row.
* **Start Section:** The starting location of a section is determined by adding the lengths of all previously defined rows. If it is the first row, then the starting point is at the top of the pile.
* **End Section:** The position of the end section is determined by adding the distance defined in this row to the sum of all previously specified rows.

**Section Orientation:** Rotates the pile section; when set to the default value of 0, the X direction in the section editor aligns with the longitudinal direction, while the Y direction represents the transverse direction.

**Pile Section Type for SSI\[Circular, Rectangular, H-Shaped]:** Specify the type of the section. This input will affect the effective diameter calculations that are needed by soil material models, unless the section is circular.

**Soil Set:** Assign the Soil Set. Soil Sets are defined under the Soil Structure Interaction tab. For more information, please refer to the [Soil Set](/templates/steel-i-girder-bridge-workflow/substructure-sig/soil-structure-interaction-sig/soil-set-sig.md) page.

**Mesh Size:** Specify the length of the finite elements of the pile.

### Analysis Settings:

**Final Embedment Length:** Enter the final embedment length. This value can be higher or lower than the initial embedment length.

**Initial Embedment Length (readonly):** This is a read-only value calculated based on the inputs you have entered in your model. The displayed value is the pile length embedded within the soil.

**Number of Trial Lengths (Max. 40):** Enter the number of trial embedments that will be analyzed between the initial embedment length and the final embedment length. This value also indicates the number of models that will be created.

**MPTE Load Cases:** Specify the load cases that will be analyzed in the model. For details on load cases, please refer to [MPTE Load Case](/templates/minimum-pile-tip-embedment-workflow/mpte-mpte/mpte-load-case-mpte.md).

### Visual Settings:

**Show/Hide Embedment Label\[Show/Hide]:** Enable this option if you want to visually identify which model correspond to which embedment length.
