Power Query for CAE Batch Data Processing 30 Cases

30 Chapters

View Course Samples Online

Import and Consolidate CAE Solver Output Files from a Batch Run

Use Power Query to import multiple solver output files (e.g., CSV or text) from a batch simulation directory, combine them into a single table, and verify row counts and file provenance to ensure no data loss.

Clean and Standardize Variable Names and Units in CAE Result Tables

Apply Power Query transformations to rename inconsistent column headers, convert units (e.g., mm to m, MPa to Pa), and enforce data types across a multi-file CAE dataset, ensuring consistent schema for downstream analysis.

StandardizeVariable

Filter and Extract Peak Stress Records from Transient CAE Simulations

Use Power Query to filter time-history CAE results, identify maximum stress values per load case, and output a summary table of peak stresses with associated time stamps and node IDs.

Pivot and Aggregate CAE Results by Load Case and Geometry Variant

Transform a flat CAE results table into a pivot summary that aggregates mean and maximum displacement by load case and design variant, using Power Query

Merge Mesh Metadata with Simulation Results Using Power Query Joins

Join a CAE results table with a separate mesh metadata table (containing node coordinates and element types) using inner and left outer joins in Power Query, enriching results with spatial context for region-based analysis.

MetadataSimulation

Handle Missing and Outlier Values in CAE Batch Outputs

Implement Power Query steps to detect missing values, replace them with interpolated or default values, and flag outliers beyond a specified threshold in a batch of CAE result files, documenting the cleaning logic.

Parse and Extract Key Metrics from CAE Log Files

Use Power Query to parse unstructured CAE solver log files, extract convergence status, iteration counts, and warning messages using text functions, and produce a structured table for batch run monitoring.

CAEunstructured

Unpivot Wide-Format CAE Results into Tidy Data for Analysis

Convert a wide-format CAE results table (with time steps or load cases as columns) into a tidy long format using Power Query

Create Custom Columns for Derived CAE Metrics (e.g., Safety Factor)

Add custom columns in Power Query to compute derived CAE metrics such as safety factor from stress and yield strength, and validate calculations against a reference subset.

Group and Summarize CAE Results by Element Type and Material

Use Power Query

Append Multiple CAE Result Sets with Schema Alignment

Append several CAE result tables from different solver versions or formats, aligning columns by name and handling missing columns, to create a unified dataset for cross-version comparison.

Conditional Replacement and Mapping of CAE Result Codes

Apply conditional logic in Power Query to map numeric result codes (e.g., status flags) to descriptive labels, and replace invalid codes with nulls, ensuring consistent interpretation across batches.

ConditionalReplacement

Extract Time-Step Data from CAE Filenames and Folders

Use Power Query to parse folder and file names to extract time-step or load-case identifiers, adding them as columns to the combined CAE dataset for traceability.

Rank and Filter Top N Critical Locations from CAE Results

Use Power Query to rank nodes or elements by stress or displacement, filter the top N critical locations per load case, and output a table for focused post-processing.

CriticalLocations

Merge CAE Results with Test Data for Correlation

Join CAE simulation results with experimental test data (e.g., strain gauge readings) using Power Query, aligning by location and load step, to prepare a correlation dataset.

Split and Parse Composite CAE Output Strings

Use Power Query to split delimited strings in CAE output (e.g., combined node ID and coordinates) into separate columns, and parse numeric values from text for further analysis.

Handle Large CAE Datasets with Query Folding and Performance Tuning

Optimize a Power Query transformation on a large CAE dataset by leveraging query folding where possible, reducing columns early, and filtering before expansion, then measure refresh time improvement.

Create a Parameterized Query for CAE Batch File Paths

Build a Power Query parameter to dynamically specify the folder path for CAE batch results, enabling reuse of the same query across different simulation runs without editing steps.

ParameterizedCAE

Detect and Remove Duplicate CAE Records

Use Power Query to identify and remove duplicate rows in a CAE results table based on key columns (e.g., node ID and time step), and report the number of duplicates removed.

Transform CAE Results for Histogram and Distribution Analysis

Use Power Query to bin stress values into intervals and compute frequency counts, preparing data for histogram plotting or statistical distribution analysis.

Merge and Compare CAE Results from Two Design Iterations

Join two CAE result tables from different design iterations, compute differences in key metrics (e.g., max stress), and flag significant changes using Power Query.

Extract and Structure CAE Solver Settings from Input Decks

Parse CAE input deck files to extract solver settings (e.g., time step, solver type) using Power Query text parsing, and create a settings table for batch run documentation.

Handle Multi-Level Headers in CAE Result Tables

Use Power Query to promote and demote headers, fill down merged cells, and flatten multi-level headers in CAE output tables to create a clean flat table.

Create a Date/Time Dimension from CAE Simulation Timestamps

Use Power Query to parse timestamps from CAE output, extract date and time components, and create a custom column for elapsed simulation time for time-series analysis.

Date/TimeDimension

Filter CAE Results by Spatial Bounding Box

Use Power Query to filter CAE nodes within a specified bounding box (x, y, z ranges) by applying conditional logic on coordinate columns, enabling region-specific analysis.

Aggregate CAE Results Across Multiple Load Steps Using List Functions

Use Power Query list functions to compute cumulative maximum stress across load steps for each node, demonstrating advanced aggregation beyond simple Group By.

Validate CAE Data Integrity with Row Count and Null Checks

Implement Power Query checks to compare row counts before and after transformations, count nulls in critical columns, and output a validation report for a batch of CAE files.

Export Transformed CAE Data to Multiple Formats for Reporting

Use Power Query to output cleaned CAE data to CSV and Excel formats, and optionally load to a data model, ensuring the export preserves data types and column order.

Document Power Query Steps for Reproducible CAE Data Processing

Add descriptive comments and rename query steps in a Power Query transformation applied to CAE data, creating a self-documenting query that can be audited and reused.

Troubleshoot Common Power Query Errors in CAE Data Loading

Diagnose and resolve common Power Query errors (e.g., data type mismatches, file not found, delimiter issues) when loading CAE batch outputs, and implement error-handling steps.
