ansys.dpf.core.core.load_library(filename, name='', symbol='LoadOperators', server=None, generate_operators=False)#

class ansys.dpf.core.core.BaseService(server=None, load_operators=True, timeout=5)#

The Base Service class allows to make generic requests to dpf’s server. For example, information about the server can be requested, uploading/downloading file from and to the server can be done, new operators plugins can be loaded… Most of the request done by the BaseService class are wrapped by functions.

Parameters:

  • server (server.DPFServer, optional) – Server with channel connected to the remote or local instance. When None, attempts to use the global server.

  • timeout (float, optional) – Fails when a connection takes longer than timeout seconds to initialize.

  • load_operators (bool, optional) – Automatically load the math operators

Examples

Connect to an existing DPF server >>> from ansys.dpf import core as dpf >>> #server = dpf.connect_to_server(ip=’127.0.0.1’, port = 50054, as_global=False) >>> #base = dpf.BaseService(server=server)
