## On this page # result:compute total strain X Last update: 31.07.2026 **Version: 0.0.0** ## Description Computes the strain from a displacement field. Only SOLID185 (B-Bar, Simplified Enhanced Strain, Enhanced Strain formulations), SOLID186 (Full Integration) & SOLID187 elements are supported. Layered elements are not supported. Thermal strains are not supported. Only one value of material properties are allowed per element for isotropic and orthotropic elasticity. Material nonlinearity is not supported Only linear analysis are supported without On Demand Expansion. All coordinates are global coordinates. Euler Angles need to be included in the database. Get the XX normal component (00 component). ## Inputs This table lists the input pins for this operator. Input pins define the data that the operator requires to perform its operation. Some inputs are required, while others are optional and provide additional configuration. Each parameter is detailed in the sections that follow the table.

To specify time/freq values at specific load steps, put a Field (and not a list) in input with a scoping located on "TimeFreq\_steps". Linear time freq intrapolation is performed if the values are not in the result files and the data at the max time or freq is taken when time/freqs are higher than available time/freqs in result files. To get all data for all time/freq sets, connect an int with value -1.. Will only be used if no displacement input is given (will be applied on displacement operator). ### scoping (Pin 1) - **Required:** No - **Expected type(s):** [`scoping`](../../core-concepts/dpf-types.md#scoping) The element scoping on which the result is computed. ### streams\_container (Pin 3) - **Required:** No - **Expected type(s):** [`streams_container`](../../core-concepts/dpf-types.md#streams-container) Optional if a mesh or a data\_sources have been connected. Required if no displacement input have been connected. ### data\_sources (Pin 4) - **Required:** Yes - **Expected type(s):** [`data_sources`](../../core-concepts/dpf-types.md#data-sources) Optional if a mesh or a streams\_container have been connected, or if the displacement's field has a mesh support. Required if no displacement input have been connected. ### extrapolate (Pin 5) - **Required:** No - **Expected type(s):** [`int32`](../../core-concepts/dpf-types.md#standard-types) Whether to extrapolate the data from the integration points to the nodes. ### nonlinear (Pin 6) - **Required:** No - **Expected type(s):** [`int32`](../../core-concepts/dpf-types.md#standard-types) Whether to use nonlinear geometry or nonlinear material (1 = large strain, 2 = hyperelasticity). ### abstract\_meshed\_region (Pin 7) - **Required:** No - **Expected type(s):** [`abstract_meshed_region`](../../core-concepts/dpf-types.md#meshed-region) The underlying mesh. Optional if a data\_sources or a streams\_container have been connected, or if the displacement's field has a mesh support. ### requested\_location (Pin 9) - **Required:** No - **Expected type(s):** [`string`](../../core-concepts/dpf-types.md#standard-types) Average the Elemental Nodal result to the requested location. ### displacement (Pin 10) - **Required:** No - **Expected type(s):** [`fields_container`](../../core-concepts/dpf-types.md#fields-container), [`field`](../../core-concepts/dpf-types.md#field) Field/or fields container containing only the displacement field (nodal). If none specified, read displacements from result file using the data\_sources. ## Outputs This table lists the output pins for this operator. Output pins provide the results of the operator's computation and can be connected to inputs of other operators or retrieved for further processing.
