https://communities.bentley.com/products/geotech-analysis/f/forum/241244/properties-of-line-drainsVery urgent, Can I use Line drains to simulate the action of a sand drain in PLAXIS 3D? If so where can I change the properties like diameter, permeability and radius of influence of a line drain? kindly help me with this issue.

Hence, it&#39;s not possible or necessary to specify a diameter or permeability. If you would like to have a drain with radius and permeability the only option is to model the drains as cylinders with a sand material set inside.<br /><br />The radius of influence cannot be specified - this is simply not how finite elements works: the radius of influence is a result of the calculation, not an input parameter.</p> <p>With kind regards,</p> <p>Dennis Waterman</p><div style="clear:both;"></div>
